RWR, radio frequencies and their interactions

just looking at the video that looks like a weirdly modeled PD search radar.
a AESA would look more like this:

AESA does exactly that though… its like the main advantage over PESA…

“The primary advantage of an AESA over a PESA is the capability of the different modules to operate on different frequencies. Unlike the PESA, where the signal is generated at single frequencies by a small number of transmitters, in the AESA each module generates and radiates its own independent signal. This allows the AESA to produce numerous simultaneous “sub-beams” that it can recognize due to different frequencies, and actively track a much larger number of targets. AESAs can also produce beams that consist of many different frequencies at once, using post-processing of the combined signal from a number of TRMs to re-create a display as if there was a single powerful beam being sent. However, this means that the noise present in each frequency is also received and added.”

one may also add some disadvantages of AESA radar over Parabolic antenna PD radar

  • much smaller maximum scannable field as long as the antenna is static (~60°)

  • Large Radar cross section as the Antenna is a flat Radar reflective surface compated to the parabolic surface of a Mechanical radar

those are btw the reasons why the CAPTOR-E on a Tranche 4+ Typhoon are mounted at an angle on a turntable

That is one of 3 radar scan patterns. I call it E low, as it is used in game on electronically scanned radars with low elevation.
We have MSA radars

Low E radars (including ASRAD) where they jump across the whole elevation scan

And High E where they do certain elevation zones at one time, used on radars with high elevation

oh yeah, agreed.

minor adjustment: its ± 60 deg so a 120 deg total angle of scan in a cone. but yes.

Edit, i was wrong

at least on jets that cross section is somewhat hidden by the nosecone that goes over the radar.

I think almost all modern jets with AESA radar has them on an angle and rotate them for a wider FOV.

Ony ECRS on EF and Raven on Gripen use gimbals for their AESA as of now.

and AESA would then look like the Low E but jumping in horizontal direction at the same time over the FOV while rotating.
its just fewer beams the longer range you scan in and the more targets you track in TWS.

yes? i don’t understand what you mean, isn’t a gimbal also rotating the radar?

It’s mechanical scanning in addition to the Electronic beam scanning. This is useful since there are hard limits on the gain for T/R modules(Sidelobes) and so improves off axis performance which is important when performing certain BVR maneuvers (Crank).

No, most AESA radars are not on gimbals, but are solid mounted

Gripen and EF have gimbals, that allows them to move it around, just like MSA

That is the case for plane mounted AESA (as they lack the gimbal most of the time, and those with gimbal do the same thing), but it might not be for ground based. I failed to find data about modern scan patterns for ground radars

oh, i read it as if you ment that gimbals were not a rotating mechanism. but yes.
i think there are more jets with movable radars. in addition to those you mentioned (found in about 10 min, there are probably more):
SU-57.
F-16’s newest radar upgrade.
Mirage 2000-5
F-15E

the nosecone doesn’t hide the Radar from another Radar

the nosecone is Invisible to radar

It has main radar that is not on gimbal
image
but it employs side radars to extend horizontal coverage
image

Isnt that its radar?

Isnt that its newest radard?

Su-57, yeah, i misread.
I ment the SU-35:

Mirage 2000-5
According to Thales This is what is on Mirage. the picture you sent is a testbed. Edit: although, that might be a regular PD radar… hmmm not sure.

F-16:
i though this was?

Spoiler

F-15E:
I misremembered an image i had seen previously, you are correct. what i remembered was the old PD radar being on a gimbal. like this:

makes sense :) otherwise it would also block its own radar XD

Thats APG 68

It is not AESA, it is MSA

Irbis-E is PESA

Huh, the more you know :) thanks for the information! :D

Is there anything stopping them from laying the radar out in like a cone shape to have nearly 360 degree coverage?

you mean like that?
