摘    要:众所周知,水下声信道是相干多途信道,信号在信道中的多径传播使得接收信号序列复杂化,因而极大地增加了信号处理的难度。对于水下目标跟踪系统,从带有干扰的接收数据中挑选出直达脉冲是系统正常工作的必要前提。本文着重介绍了系统软件的核心部分——专家系统,它用于实时跟踪系统的数据预处理,负责在多途干扰背景中提取定位解算所需的有效信息。通过计算机仿真、松花湖试验和海上试验的验证,专家系统可以准确地挑选出直达脉冲和最佳解算阵元,因而确保了系统的定位精度与测深精度。

关 键 词:专家系统 水声跟踪 多途干扰 水声定位 数据预处理

Abstract:It's well known that underwater acoustic channel is a coherent multi-path channel, which brings difficulties in signal processing because of the complexity of the received signal sequence. For 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 presented in this paper. By means of simulation, lake trial and sea trial, it is proved that the expert system can sort out the direct pulses and the right buoys effectively so as to ensure the precision of position and depth location for the underwater target tracking system.
Keywords:Expert system   Underwater acoustic tracking   Multi-path interference   Underwater acoustic location
