自适应滤波技术在水声信号处理器中的应用

Application of Adaptive Filtering Technology in Underwater Acoustic Signal Processor

针对海洋环境噪声大、干扰信号强的特点,在水声信号处理器研制中,采用自适应滤波模块对海洋水声信号进行处理。实验表明该方法具有良好的滤除噪声和抗干扰能力,顺利实现了海洋复杂环境下的水声信号处理。

To deal with the ocean environment with strong noise and high disturbance signals in the development of the underwater acoustic signal processor, the method of adaptive filter module is proposed to process the underwater acoustic signals. Experiments show that the method has good ability of filtering noise and anti-interference. The underwater acoustic signal processing in complicated ocean environment is realized successfully.
