Abstract: The formation of a hologram of a noise signal from an underwater source against the background of distributed interference is described. An expression is obtained for the bandwidth of the angular distribution of the spectral density of the noise signal on the hologram. The minimum duration of the noise signal is estimated, which determines the maximum detection range of the noise sound source. An algorithm is presented for determining the parameters of holographic processing that realizes the maximum detection range. Holographic processing of noise signals is considered using a single vector-scalar receiver and linear antennas.
Keywords: holographic processing, underwater noise source, receiving system, signal duration, detection range
