6s since the locked-on update that came in
8s the spring of 2019 war thunder has been
12s regularly receiving vehicles equipped
14s with radar systems
16s various types of radar help control your
18s vehicles detect targets at longer
20s distances and in poor weather conditions
23s today radar systems can be found on
26s planes helicopters ground vehicles and
29s even naval vessels but what are those
32s types of radar and how are they
34s different
35s [Music]
38s the first type is a radar range finder
42s it allows you to lock on targets along a
44s fighter's boresight line and
46s continuously measure the distance to it
49s the data feeds into the gun's gyro site
51s to calculate lead
53s radar rangefinders use a wide fixed beam
55s which improves detection and lock-on
58s time
59s but this system comes with some flaws as
61s well they're affected by ground clutter
64s and thus incapable of detecting targets
66s at distances exceeding the fighter's
68s altitude
72s to control this radar you only need one
74s button lock radar irst on target it's a
78s simple on off switch once you turn it on
80s it locks onto the first target in the
82s direction of your flight and tracks it
85s if the target is lost the rangefinder
87s starts looking for it automatically
93s the next type of radar is the search
95s radar with a fixed beam its working
97s principle is very similar to
99s rangefinders they too use a wide fixed
101s beam to scan your environment in real
103s time and they suffer from ground clutter
106s just as much so they can't detect
108s objects at distances greater than your
110s fighter's altitude the main difference
112s found on this radar is its ability to
114s track both distance and direction of
117s your target to use this radar you'll
119s need to assign a button for switch radar
122s irst search on off
129s now let's talk about more modern
131s scanning search radar these can be found
134s on both planes and most anti-aircraft
136s systems this radar can provide both
139s distance and direction data about
141s targets employing a narrow beam that can
143s perform azimuth scanning of either a
145s sector or the full 360 degrees
149s due to this feature it can't show
150s real-time data the display is only
153s updated after the scanning beam finishes
155s its sweep on the plus side this type of
157s radar has a larger range than fixed beam
160s radar they can also be divided into two
163s subtypes the first one scans the whole
165s sector vertically using a wide beam
168s these radar systems are susceptible to
170s ground clutter and cannot find the
171s target's elevation
173s the second subtype scans a few bars
176s moving along a narrow beam vertically
178s when the beam scans an area above the
180s horizon the ground creates much less
182s clutter moreover these radar systems can
186s find the target's approximate altitude
188s to control scanning search radar systems
190s you can use the following functions
193s switch radar irst search on off change
196s scope scale change search mode select
199s target to lock and change radar irst
203s mode
206s [Music]
208s now we've mentioned ground clutter a few
210s times already up until the mid-1970s
213s fighters suffered significant
215s interference from it preventing beyond
217s visual range missile launches detecting
220s targets below the horizon level has
222s always been difficult because the beam
224s would touch the ground
225s war thunder can indicate the clutter in
227s radar scope and show its strength level
230s in addition to that target detection may
232s be harder if the fighter flies at a low
234s altitude it happens due to the radar
237s side lobes emitting and receiving
239s reflected signals
241s if the distance to your target is less
243s than your altitude ground clutter isn't
245s a problem since the enemy shows up in
247s your scopes before the clutter does
250s but all of this is only true for older
252s pulse radar systems technology progress
255s taught radar systems to look down
260s these systems use moving target
262s indication or mti for short and the
265s pulse doppler principle or pd both
268s technologies allow the radar to separate
271s ground clutter and moving targets by
273s their radial or doppler speed
276s pd radar systems generally provide
278s better object separation and better
280s detection range in look down modes
282s compared to mti radar still early pd
286s radar models like the one found on the
288s british phantom cannot range targets in
290s search mode only showing direction and
293s radial speed
294s moreover both types share a flaw they
297s cannot detect targets below the horizon
300s if the targets are flying perpendicular
302s to the radar beam
304s early pulse doppler and mti radar
306s systems also experience issues with
308s detecting tail on targets because
311s terrain moves at a high speed relative
313s to the fighter and ground clutter
315s prevents detecting targets flying along
317s the same direction
319s more advanced radar systems such as the
321s ones found on the f4 ej kai and the j37
325s viggen can detect targets well both tail
328s on and moving towards them
334s by the way ground clutter is just as
336s much an issue for ground radar systems
338s pulse doppler and moving target
340s indicator technologies had been
342s implemented there even earlier than on
344s aircraft since ground radar moves less
346s and almost not at all compared to
348s aircraft radar they show a more reliable
351s performance
352s [Music]
355s the increasing popularity of radar
357s naturally led to the invention of
359s countermeasures we call it chaff chaff
362s is basically pieces of foil that show up
364s as fake radar targets aircraft equipped
367s with early radar systems see fake
369s targets in search mode and have troubles
371s in tracking mode as well
373s meanwhile pulse doppler and mti radar
376s systems are resistant to chaff they can
378s ignore countermeasures in search mode
380s along with the ground clutter in
383s tracking mode chaff only works if the
384s target is flying away from the fighter
387s or moves across its course
389s no chaff can prevent lock-on if the
391s target is flying at the radar
400s still radar systems are used for more
403s than target detection on fighters
405s they can also be employed to hit targets
407s with semi-active radar seekers these
410s seekers work much the same way as
412s regular radar the only difference is
414s that the emitter is found on board the
416s fighter while the receiver is on the
418s missile itself
419s there are two types of radar seekers the
421s first one is a pulse radar seeker these
424s can be found for instance on the r3r and
426s the r530 missiles
428s much like pulse radar found on fighters
431s they're susceptible to ground clutter
432s and can be fooled by chaff the more
435s advanced type is continuous wave seekers
437s like the r23r the r24r and the sparrow
442s they work like the pulse doppler radar
444s and use doppler filtering to separate
446s ground clutter and chaff
448s much like pd radar they cannot track
450s targets flying below the horizon level
452s across the line of sight and their tail
455s on range is much shorter
460s another type of radar found on aircraft
462s and ground vehicles is tracking radar
465s it's used for automatic target tracking
468s gun aim and air-to-air missile launches
471s they can use both fixed and tracking
473s beams measure distance and find the
475s target's direction
477s for instance the mig-19 pt radar uses a
480s fixed beam and its maximum tracking
482s angle is only seven degrees around the
484s bore sight line
485s meanwhile the f3 d1 uses a tracking beam
489s so its maximum tracking angle reaches up
491s to 60 degrees around the bore sight line
495s moreover such radar systems have a
497s significant range advantage the radar on
499s the tunguska and the gephard use a
502s tracking beam too and can also rotate
504s 360 degrees in azimuth or move between
508s minus 10 and plus 90 degrees in
510s elevation
511s [Music]
515s the tracking radar on the d3d1 and the
517s mig-19pt can lock onto targets in a
520s narrow sector at a specific distance
522s along the course of flight
525s the tunguska and the guipard radar
526s systems can acquire a target by
528s designation from the search radar in
530s third person view or by optical site you
533s can cycle targets to lock on by pressing
536s select radar
537s irst to lock or with a moving target
540s queue that can be controlled by keys
542s assigned for horizontal radar irst
545s target queue control axis
547s and vertical radar slash irst target cue
550s control axis
552s these axes only work if you disable the
554s option called target's cyclic switching
557s of aircraft radar for planes and
558s helicopters or targets cyclic switching
561s of ground radar for anti-air vehicles
564s and vessels a tracking radar performs a
566s fine search in the specified area to
569s lock onto a target ranging direction and
571s distance
572s if there's more targets in the area it
574s can lead to a lock on the wrong plane or
577s helicopter moreover a target with a high
580s angular velocity at close range can move
582s out of the tracking radar's detection
584s area rendering the fine search useless
587s it might look like a bug but it's a real
589s life problem for radar systems
591s replicated in the game
593s [Music]
596s to control the radar you can use the
598s lock radar irst on target button on
601s aircraft this command turns the radar on
603s and off which then automatically locks
605s onto a target tracks it and tries to
608s reacquire it if it's lost on
610s anti-aircraft vehicles this command is
612s used to acquire a target by search radar
615s designation or by optical sight
621s you should keep in mind an unpleasant
623s phenomenon happening when tracking
625s low-flying targets less than 100 meters
627s above the ground
628s due to signal reflection the so-called
631s multipath effect the direction to the
633s target may shift lower
635s this effect appears even when the radar
637s system has a pulse doppler or an mt1
640s mode
641s in such cases an aa missile operator
643s might want to switch to the optical
645s tracking system if they have one or
647s target the missile manually
649s as for fighters with semi-active radar
651s homing missiles the only thing that'll
653s help them is a high angle of attack
658s [Music]
660s and now it's time to talk about the
661s system that adds this irst part to every
664s command we've mentioned
666s irst stands for infrared search and
669s tracking it's a passive sensor that can
671s detect a target's infrared signature
674s some radar such as the one found on the
675s mig-23 can only give the direction to
678s the target
679s others like on the stormer are equipped
682s with a laser rangefinder that can add
684s distance data to switch to the infrared
686s search and track sensors use the
688s following command switch between radar
690s and irst
692s [Music]
695s we'd like to finish this video with the
697s most complex systems combined search and
700s track radar capable of tracking targets
702s in multiple ways
704s for example the mig-21 smt in air combat
707s maneuvering mode can acquire targets in
710s a narrow sector along the bore site
712s direction the mirage 3e in beyond visual
715s range mode can attack the selected
717s target even out of sight
719s the phantom's radar systems can acquire
721s targets in both modes
723s let's go over the controls one more time
726s with search and track radar systems
728s switch radar irst search on off switch
732s between radar and irst
734s change scope scale change search mode
737s select target to lock
739s change mode
741s beyond or within visual range combat and
744s lock on target
746s [Music]
748s that's it for today friends our long
751s story about everything that has radar in
753s it has come to its end
755s we wish you less clutter and more beyond
757s visual range frags
761s [Music]
787s you
