| 摘 要： | 通过对水声信号进行参数估计可以获得信号的频率、制式和周期等参数信息,传统的水声信号参数估计的实现方法过程繁琐,工作量大,开发周期长且可靠性较低。采用美国国家仪器公司最新推出具有高实时性的嵌入式控制和采集平台NI-CompactRIO以及Labview图形化开发环境,在该平台上实现了谱线比值法测频、信号转发和匹配滤波三种参数估计算法,提高可靠性的同时也缩短了开发周期。

| Abstract: | Three algorisms are commonly used for underwater acoustic signal parameter estimation： 1.the method of measuring signal frequency requency with the ratio of maximum spectrum line to sub-major spectrum line;2.the signal retransmission is to send the received signal with added feature information;3.the matched filter is to carry out convo-lution of matching function and received signal to determine the receiving signal.The latest real-time embedded de-velopment platform NI-CompactRIO and the Labview development environment are selected to implement the above three algorithms.Experimental results prove the correctness of the algorithms,and verify the feasibility of NI-Com-pactRIO platform. |
