The authors proposed a method of coding and signal processing for the sonar fast-moving objects detection tasks. The method is based on the frequency manipulation of signals and provides effective power consumption of the transmitter, while maintaining high range and speed resolution within given noise immunity. The results of the research showed its effectiveness in the correlation processing of signals that are reflected from fast-moving underwater objects and distorted due to the Doppler effect.

Keywords:Sonar, frequency manipulation, Doppler effect, correlation processing.
