声纳主动探测中的最佳波形选择问题

Waveform Selection Proposition in Active Sonar Detection

主动声纳发射信号的波形选择较灵活,如果选择不恰当,则会在一定程度上影响声纳作战使用效能。从现有声纳发射信号波形的时频特性出发,详细分析了海洋环境、战术任务对波形选择的影响,着重论述了声纳发射波形选择的基本原则,并通过案例进行验证。

It is sometimes hard for the active sonar to select appropriate waveform to transmit because of multiple choices,which affects sonar operational potency to a certain degree.Based on the time-frequency characteristic of the familiar sonar waveforms,this paper analyzes in detail the influences of the ocean circumstance and the tactical mission on sonar waveform selection.The basic principles of the waveform selection is summarized and is proved by some cases.
