Abstract: The formation of an interferogram and a hologram of a moving underwater noise source using linear antennas is considered. The relationship between the spectral density of the hologram and the aperture and the angular dependence of the received field is derived. Antenna gain has been estimated. The issue of the limiting signal-to-noise ratio at which the holographic processing remains operational is discussed. An analytical expression is obtained that establishes a relationship between the signal/noise ratios at the output and input of the antenna. Conditions are formulated under which the interferogram of the source is not distorted.

Keywords: shallow water area, interferogram, hologram, noise source, linear antenna, signal-to-noise ratio, antenna parameters
