Abstract : A low frequency sonar beamformer system is described using both frequency scaling and velocity scaling. The system is characterized by the use of frequency adding in the frequency scaling section, and the use of a variable frequency oscillator therein which is controlled to compensate for target range, frequency of received energy, and local water conditions.
