Abstract

The detecting error of azimuth with anti-helicopter mine (AHM) based on narrowband filter and the influence factors of the error are analyzed when the frequency of target sound source is the same as that of interfere sound source in perfect sound field. The analysing results show that the larger the flare angle of two sound sources to the AHM is, the larger detection error of azimuth becomes; because of the Doppler effect, the narrowband filter can decrease the detecting error to meet the system requirements under certain conditions. This lays the foundation of solving the problem with the mine field formed from some AHM.
