Now since you've asked please get your self updated on how Radars are jammed using electronics.
A simple question 'what actually a jammer or EW suites is??'
They also contain T/R modules and concentrate their energies on target determined by the main radar, actually they are like mini radars that can hop onto different frequencies and those frequencies are amplified by the main radar energy generators to jam an inferior/less powerful radar like KLJ-7 now with the advent of packing small transmitters in a large aperture of a radar the frequency hopping part can be done by main radar itself so separate EW suits aren't req.
Ever heard AN/APG-81 jamming the mighty AN/APG-77(Radar on the F-22A Raptor) which is an AESA with 2200 T/R modules.
Actually you need to know a lot and I am unable to think where do I start from so it would be better if you did a little painful job of Googling about the same.
By the small and low powered pulse droppler radars like KLJ-7 can't switch many frequencies so it is'nt difficult to jam them.
Right..
An ESA isnt magic.. but it is a powerful advantage..
each T/R module usually ends up transmitting a small amount of power compared to the monster's that sit on the Russian jets like the bars..
Its when they work in unison that they are effective.
Their ability to instantaneously transmit across a wide band of frequencies offers the secondary jamming ability.
However.. older jammer's too have had this capability of switching across multiple frequencies at pretty much similar rates ..
The big advantage was being able to steer the beam and perform multiple tasks at the same time.
Now how does an AESA radar match up against a "inferior(made by CHina.. used by Pakistani's so it must be so.. I know the thinking process in the east)"..
First.. the AESA can allow the user to jam the standard pulse doppler radar... well.. great.. you just gave away your presence..
So our intrepid J-11/JF-17 "inferior" pilot decides to use his passive sensors to pick you out, since whilst you are jamming you are transmitting all the power you have on that thing.. here is a nice Sd-10B for you..
wait... here is a smart pilot.. he decides to use his AESA in LPI mode.. which means letting its T/R modules transmit smaller ,less powerful beams at the "inferior" aircraft each at a different freq .. and see's where there is a common spike in the return of those beams..
Problem with using less power is that your detection range decreases.. So you have to get closer to pick out the inferior jet.
But wait.. your jet has a big huge arse that stick out like a sore thumb.. so the inferior radar on the inferior jet with all its lack of capability still picks you out..lo and behold.. where is that SD-10 coming from??
You act smart.. you hit those israeli or European jammers.. they blank out the link between the inferior jet and the inferior missile..
But wait.. that inferior missile has a home on jam capability.. it picks you out anyway.. and follows your jamming home like a lost puppy..
So you google some more.. and decide to use your maneuverability to outfly the missile..whilst your GIBS gets off a shot or two at the inferior jets..
Google for the result..
P.S
No pakistani dare mention that the inferior jet will gets its AESA in the next batch.. and will be retrofitted on the last ones..
even thought the Opposition jets with the supposed AESA are without them.
No pakistani dare mention that the AESA upgrade for the J-11B that is being screamed about at every other chinese forum is there as well.. or that the J-10B starts with the AESA in the first place..
Blasphemy to do so after all..
