A scheme of construction of imaging systems based on a complex modulated illuminating beam and the received echo signal processing is proposed, which involves the extraction of the modulated component and its matched filtering is discussed. The approached model of a signal taking into account the effect of surface waves and multiple scattering in water is constructed. The system limiting longitudinal and transverse resolutions determined by random light refraction on the surface and scattering in water are estimated. Characteristics of imaging systems with extremely high frequency of beam modulation are estimated.
