Angular resolution is one of the most important performance measures in a long-range SONAR. It is necessary to increase array aperture size (AAS) for better angular resolution. Usually, the AAS of SONAR is increased by using more receiving sensor ele

The underwater acoustic noise radiated from the propellers of surface and underwater vehicles is characterized as high-frequency broadband noise modulated by low-frequency narrowband noise. Since the modulation is affected by propeller rotation speed
