摘要
在鱼雷声自导中,信号设计与抗混响能力是声自导技术研究的重要内容。目前实际工程应用中声自导发射信号大多仍以常规信号形式(如CW,FM)为主,其自导性能及抗混响能力还有待进一步提升。本文从声自导设计的角度探讨了包括CW-CW,LFM-LFM,CW-LFM,Costas等多种可用于声自导的复杂信号形式,并以ROC曲线分析了信号检测概率等问题;然后利用Q函数及信号-混响原理图分析各信号的抗混响性能。仿真结果表明上述各复杂信号较常规信号具有更优的性能,在声自导中具有较好的工程应用前景。本研究将为新型声自导设计提供技术参考。
In the acoustic homing of torpedo,signal design and anti-reverberation ability are important contents in the research of acoustic homing technology.At present,most of the acoustic homing emission signals in actual engineering applications are still in the form of conventional signals(such as CW,FM),and their homing performance and snit-reverberation capability still need to be further improved.In this paper,from the perspective of acoustic homing design,a variety of complex signal forms,such as CW-CW,LFM-LFM,CW-LFM,Costas,which can be used for acoustic homing,are discussed.The problem of signal detection probability is analyzed by ROC curve;then the Q function and signal-reverberation schematic are used to analyze the anti-reverberation performance of each signal.The simulation results show that the above complex signals have better performance than conventional signals,and have better engineering application prospects in acoustic homing.This study will provide a technical reference for the design of new acoustic homing.
