ES-3701U is a high-performance radar ESM for submarine applications. The system uses a circular phase interferometer for monopulse angle of arrival (AOA) measurement to achieve high accuracy. ES-3701U implements advanced signal algorithms for positive emitter identification and library classification. It also provides robust interference removal to remain functional in a littoral signal environment while removing multipath to reduce the effects of reflected signals.
