Modern EW Systems Require Efficient RF Power Management
One aspect of electronic warfare (EW) that is a constant challenge is keeping up with the ever-increasing sophistication and persistence of threat radars. For example, today’s threat radar detection systems must quickly determine whether or not the target is real or has been created by a digital RF memory. DRFMs can be used to capture a signal, digitize it, reconvert it to analog, modify it, and then rebroadcast it. Using a library of known emitters, the DRFM can alter a target’s radar cross section, range, speed, angle of arrival and direction, and even create false targets behind the target (reactive jamming) or ahead of it (predictive jamming). When these techniques are successful, the threat radar detection system may mislocate or misidentify a target.
