| description | The invention discloses an active sonar interference suppression method for a suppressing interference source, and relates to the field of acoustic signal processing target recognition. According to the method, periodic interference signals in an interference direction are extracted by using the repetition periodicity of suppressing interference, and adaptive filtering is performed on beam signals in all directions in an interference range by using the periodic interference signals as reference signals, so that interference suppression of full-space multi-beam signals is realized. According to the method, periodic suppressing interference can be effectively suppressed, the active target detection rate under the interference background is greatly improved, and improvement of the anti-interference capability of sonar equipment can be supported.
本发明公开了一种针对压制式干扰源的主动声纳干扰抑制方法，涉及声学信号处理目标识别领域。该方法利用压制式干扰的重复周期性，对干扰方位上周期干扰信号进行提取，以此为参考信号对干扰范围内各方位上波束信号进行自适应滤波，实现全空间多波束信号的干扰抑制。该方法可对周期性压制式干扰进行有效抑制，极大提高了干扰背景下的主动目标检测率，可支撑声纳设备抗 |
