摘要
Abstract
In order to detect acoustic fuse echo for anti-torpedo torpedo (ATT) in strong reverberation noise background, an echo signal detection method is put forward by using Doppler frequency feature on the basis of the characteristic differences between active acoustic fuse echo and reverberation of anti-torpedo torpedo. By using the proposed method, fewer receiving devices can search in the frequency scope from -50 kHz to 50 kHz. The operating characteristics of a receiver are simulated by Monte Carlo method. The results show that the echo signals can be detected by the FFT-based detection system of active acoustic fuse echo for ATT in strong reverberation noise background. And the detection probability is higher than 0.999 5 even if the false alarm probability is 10-4 when the SNR is higher than 3 dB.关键词
