主动声纳 混响抑制 模糊度函数 多普勒
【摘 要】 波形设计是影响主动声纳探测性能的重要因素。推导了SFM信号的模糊度函数,根据模糊度函数分析了SFM信号在混响背景下的检测性能,并与CW、LFM信号进行了比较。理论分析与湖上试验验证了在中等多普勒情况下SFM信号抗混响能力最优的结论。本项研究为主动声纳发射波形选择提供了参考。
-Active sonar reverberation suppression ambiguity function Doppler Abstract waveform design is an important factor of the impact of active sonar detection performance. The SFM signal ambiguity function is derived, based on the ambiguity function the SFM performance of signal detection in the context of reverb, and compared with CW, LFM signal. The theoretical analysis and experimental verification of SFM medium Doppler case the signal resistant reverb capacity optimal conclusion on the lake. Study provide a reference for active sonar transmitter waveform selection.
