you’re never scanning all Bands, you’ll have your Reciever(s) Fitered to the Frequency band(s) that you’re expecting to see something in, and it doesn’t matter if that radar is sending in the X band like a CASTOR-E (AESA) or the S band like a USN ship, as long as you can recieve this band you will always be able to pick up the direction of that Sending radar
you’re not looking for rare patterns in an otherwise jungle like Band, you’re looking at a band that nothing else uses and any contact there will be a Radar, you don’t even need to look for a specific pattern then unless you want to definitely Identify the Specific Radar that’s looking at you
the reason why the rumour came up that they’re invisible to RWR is because AESA radars have to use different frequency bands than older PD radars to function, those bands were entirely filtered out on older RWR designs
No and yes. Emitters can work independently. But it’s not 1 frequency per emitter. You need to have several of them at the same frequency to do get interference between the waves which allows to form a beam.
Most of the LPI modes are through signal’s waveforms, scanning patterns and beam patterns
And don’t even dream. The radar dev wont do it and would end up with some nonsense. Which is what happens when they don’t pay to get a radar consultant from all the premium F4S, F5, 23ML sales.
Considering the simplifications already done for the sake of gameplay/balance/etc, I would not expect AESA to have any specific or advanced features. I’d imagine it’d have smaller notch windows and still be susceptible to multipathing.
Essentially a better PD radar with insane scan rate. I would like for it to also have the same TWS the F-14A had at launch but that’s copium from me.
yea but not scanning in multiple frequencies at the same time, that only AESA can do because PESA and Parabolic Antenna based radars both lack the Amount of antennas required for using multiple Frequencies at once
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.”
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.
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).
