Search Radar ECM/EA Simulator

FUNCTION: Tests the effectiveness of electronic countermeasures/electronic attack (ECM/EA) equipment and techniques for jamming airborne search and targeting radars.DESCRIPTION: The Search Radar ECM/EA Simulator (SRES) is an electronic laboratory for developing EA techniques and for testing EA equipment. It simulates the engagement between an airborne threat search radar and a group of surface ships and aircraft that use EA as part of their defense. The simulation generates RF signals in real time that would be present in the threat radar receiver as measured from the radar echoes and EA. These signals are processed by the radar receivers and presented on radar displays for man‑in‑the‑loop determination of EA effectiveness. An effective EA prevents the radar operator from determining the preferred target's location. The simulator is housed in a room having both 60- and 400-Hz electrical power. A personal computer interfaces with the microwave attenuators and switches to generate the simulated radar signals and provides the controls for the desired scenario under test. SRES uses human radar operators to achieve actual man‑in‑the‑loop target determination and EA effectiveness.INSTRUMENTATION: Resident EA equipment includes noise sources, false target generators, and AN/SLQ‑32 techniques generators. Radar equipment includes a coastal defense radar system, two plan position indicators (PPIs), A and B scopes, and other radar receivers. Additional data recording devices are a radar scan converter (RSC) providing S-VHS video recording and monitoring of radar video presentation, various oscilloscope displays, and microwave spectrum analyzer with plotter for recording its display presentation.
