Understanding the Peculiarities of Acoustical Monitoring of Moving Objects in Shallow Water Areas

The article considers peculiarities of underwater monitoring of moving objects in the shallow water

areas, particularly seaports. These areas are characterized by a multitude of factors influencing the

efficiency of detection. Nonstationarity conditions of sound propagation and specific interference

caused by shipping are the major factors. The various algorithms for the space-time signal processing

have been tested and some experimental results are presented. It has been shown that the use of

clipped mode in conjunction with the correlation processing of wideband signals and subsequent

speckle tracking allow realizing high efficiency of monitoring.
