FIELD: physics, radio.
SUBSTANCE: method of detecting objects inside a mud line can be used in the design of apparatus for searching for objects at the bottom under a layer of soil and invisible for such sonar detection apparatus as a side-scan sonar device. In the disclosed method, the detection range of objects inside the mud line increases owing to more efficient excitation of the near-bottom wave, as well as due to that the information component used is not the soil component, but the water component, whose attenuation is significantly less. Use of processing algorithms of the type of aperture synthesising and multibeam compensation in the disclosed method of detecting objects inside the mud line enables to maintain high resolution of the method and long operational range.
EFFECT: long operational range with high resolution.
