FIELD: ocean surface radar for aircrafts.
SUBSTANCE: invention can be used in search and detection of underwater sound sources. The claimed method uses two-position sighting of the sea surface with a "quasi-mirror" side-scan radar, which provides a viewing area with width of 3H, where H is the flight altitude of the aircraft, with a high specific effective scattering area (SES) of the surface of approximately 1 (0 dB). The quasi-mirror scattering mode with a high SES and the possibility of separating the frequency spectra of the vibration signal and wind waves during coherent detection of a pulsed radio signal make it possible to isolate a weak vibration signal with spatiotemporal averaging on a given area during azimuthal synthesis.
EFFECT: ensuring prompt detection of a sound source in large areas.
