| 摘 要： | 根据声呐方程与模糊度函数分析了CW、LFM与SFM等3种主动声呐波形的抗混响性能,结果表明不同多普勒情况下应采用不同发射波形。湖上静态混响测试试验验证了静止或低多普勒情况下LFM信号抗混响能力最优的结论。本项研究为主动声呐发射波形选择提供了依据。

| Abstract: | The reverberation suppression performance of three kinds of active sonar signals including CW,LFM and SFM signals are analyzed based on sonar equation and ambiguity functions.The results show that the Doppler shift introduced by target movement determines which kind of pulse should be transmitted.The lake trials under stationary conditions validate the superiority of LFM signal in reverberation suppression with very low Doppler shift.This study makes the foundation of the transmission pulse selections for a... |
