Ensuring the proper operation of Radar Warning Receivers (RWRs), Electronic Support Measures (ESM), Electronic Attack (EA), and other Electronic Warfare (EW) receivers via rapid and realistic testing is vitally important as the use of EW systems proliferate across all platforms from sea to land to air to space. D-TA’s MRSE-5000 PETS (Portable EW Training & Test System) system enables realistic and repeatable short-range (up-to 50 m) over the air testing (OTA).
