| 摘 要： | 降低测量平台处本艇自噪声能够有效地提高被动声纳设备作用距离。文章分析了参考输入中含有目标信号的本艇自噪声有源抵消器的性能。通过理论分析可以看出，随着本艇自噪声有源抵消器参考输入端信噪比的降低，系统输出端信噪比升高。同时。计算机仿真说明，只要参考输入中信号分量较少，自噪声有源抵消器仍然可以达到较好的降噪效果。

| Abstract: | Reducing the self noise of submarines can effectively increase passive sonar range in the sonar platforms. This paper analyses the effect of the signal components in the reference input on the Performance of the active self noise canceler. It can be seen from the theoretical analysis that the signal to noise ratio in the output of the canceler will improve when the signal to noise ratio in the reference input drops. Computer simulations also validate that the good attenuation effect can be obtained in the active self noise canceler if the signal component in the reference input is small. |
