However, I was wrong in inferring the reduced radar detection range in presence of jamming. That would be the burn through range from the figure you posted. So between 4-5 times lower burn through range, assuming the numbers I previously posted.
The correct interpretation, as far as I understand now, is as follows.
Assume that the Rafale-M has a 17 times lower RCS than J-15. Assume both aircraft are illuminated by the same radar. Assume both aircraft are jamming the radar. Then for the J-15 to be detected at the same (max) range as the Rafale it would need a jammer 17 times as powerful as the Rafale. The detection range can be derived from the burn through equation.
Max,
I am moving the conversation to this thread as a lot of what was discussed was cluttering the J-15 thread.
I cannot vouch for the details as they are data specific to the equation. However the principle remain true and that is there is an underlying jamming advantage in terms of power requirement associated with a RCS advantage. The burn through threshold itself is condition specific as you would appreciate.
With regards to the angular accuracy issue, it is a common problem especially with RWR.that historically had been pretty bad (10 degrees or more). There are recent advances such as with the ALR-67(V)3 on the F-18 that is down to 1 degree and the Spectra on the Rafael that is reportedly less than 1 degree. We don't know what the Chinese has but I do know that high end RWR/ESM with the high end capabilities cost. I question what one can buy when building a plane for $30 million. For example, the EPAWSS system alone planned for the F-15C cost $11 million plus a pop.

Finally be mindful of triangulation conversation because the tech level required between a static target and a fast moving target are significantly different. It is a quantum leap in capability. Don't be blinded by a bunch of non relevant red herrings.
