Sorry, but I have more faith in our SIGINT than your 'study'.
It does not mean I know more than you do on what Iran has, for all we know, YOU maybe correct. But what I mean is that signals do not lie. Cannot lie. You can be assured %100 that prior to the war, we know %99 of what Iran transmit. A 'targeting' radar do not transmit outside of the X band, for example. That is real physics, not 'Chinese physics'. You can certainly assign a meter length freq to 'target' if you want, but that would be akin to US assign the B-52 to be an air defense interceptor. Absurd, ain't it? Always, physics have the final say, no matter what the PDF Chinese assert.
SIGINT allowed US to prevail over Iran.
