Abstract

Considering the location demand of radiated noise source in underwater target, the method of location of line spectrum of radiated noise based on passive synthetic aperture method is presented. Line spectrum signal is received using single hydrophone, and azimuth sampling rate depends on the azimuth doppler band, and the received data of one-dimension is transformed into data of two-dimension. Azimuth compressing function is configured based on the range curve and the frequency of line spectrum, image of line spectrum is derived in frequeny-azimuth domain. Simulated results show that line spetrum of radiated noise can be located and distinguished, and the resolution is dependent on the azimuth doppler band.
