How often would it need to do burst ranging to improve accuracy? I wouldn't say it does it in intervals <1sec. The RWR would've to fulfill, 2 conditions. STT and nonRG HPRF (if no burst rangine after x amount if time). it would be much quicker than 1 second for sure. The error in range estimate just on radial velocity is bound to accumulate quickly because of phase noise in the doppler measurement. 32 minutes ago, marmor said: Imo, it is pushing it on hypotheticals. Not even more advanced and complex RWRs of western were able to know if there's launch as you can read on the Tornado F3 Tacman. Applying a set of data from one case to everything else is not proper research tho. We dont know what that threat system the tornado TACMAN refers to, and what specific waveform and function those threat systems use. Like everything in radar design there are multiple ways to do the same thing. By examining another system and its operation i think i've demonstrated that at minimum it's not a black and white conclusion. And there are some systems that have enough change in waveform to trigger launch warnings.
