The Influence of Scattering Hydroacoustic Signals on the Efficiency of Adaptation Algorithms When Permission Weak Signals in the Presence of Strong Interfering Sound Source

Malishkin G.S.

The current work is analyzing an interference situation in the presence of a significant scattering component within the strong interfering signals. The order of magnitude of the interval of fluctuation frequency correlation in sea environment is estimated. Simulations of direction-finding contours of the adaptive algorithms (classical and those based on the orthogonal projection with valuation of the strong signals) are carried out for resolution of the weak signals masked by the strong local source signals in the presence of the scattering component in their structure. An influence of the physical parameters of the acoustic field (the interval of fluctuation frequency correlation) as well as the parameters of the receiving channels is studied.
