Anti-multichannel Expert System for Underwater Target Tracking System

摘要

It's well known that underwater acoustic channel is coherent multi-path channel, which brings more difficulties in signal processing for the complexity of the received signal sequence. In terms of the Underwater Target Tracking System, it is essential to select the direct pulses correctly for proper operation. The expert system used for selection of valid information in the multi-path sequence is introduced in this paper. By means of simulation, lake and sea trial, it is proved that the expert system can sort out the direct pulses and right buoys effectively and ensure the location and depth precision of the underwater target tracking system.
