Those systems make RF guided A2A Missiles and SAMs blind, don't they? İ don't think they could jam modern ground radars however jamming active seeker of missiles is quite enough.
ChatGPT:
Yes, you're correct. Electronic warfare systems like the AN/ALQ-257 IVEWS and the VIPER SHIELD™ AN/ALQ-254(V)1 are primarily designed to disrupt and neutralize radar-guided threats, including air-to-air (A2A) missiles and surface-to-air missiles (SAMs). These systems employ various techniques, including jamming, to interfere with the radar signals used by these missiles to track and target aircraft.
While they may not directly jam all types of ground-based radars, their ability to jam the active seeker of missiles can indeed be highly effective in countering threats from radar-guided missiles. By disrupting the guidance systems of these missiles, electronic warfare systems can significantly reduce their effectiveness and increase the survivability of aircraft in hostile environments.
