Description: 该代码是从SPEEX中提取出来有关回声消息部分的源码
它采取的是在频域进行操作，效果比较好"
经测试，如果原始声音与用于回声消息的参考声音之间存在时钟不同步时，极易发生在回音消息算法中的反溃发散现象.
压缩包中含有测试语音文件：
Input_exsample_stereo.pcm: 8k16bit的线性pcm，含双通道语音。
vleft.pcm: 8k16bit linear pcm, 从Input_exsample_stereo.pcm 中分离出来的左声道音频。
right.pcm: 8k16bit linear pcm, 从Input_exsample_stereo.pcm 中分离出来的右声道音频。
-The code is extracted from the SPEEX news out of the echo part of the source it is taken to operate in the frequency domain, the effect is better " by the test, if the original voice message and a reference for the echo between the voice of the clock is not synchronized easily occurred in the response message algorithm in the phenomenon of anti-ulcer divergence. compressed package file containing the test voice: Input_exsample_stereo.pcm: 8k16bit linear pcm, including dual-channel voice. vleft.pcm: 8k16bit linear pcm, from Input_exsample_stereo.pcm separate the left channel audio. right.pcm: 8k16bit linear pcm, separated from the Input_exsample_stereo.pcm the right-channel audio.

Description: 舰载雷达所处的环境杂波现象比较严重。雷达工程人员发现，无论信号处理采用哪些反杂措施，雷达数据
处理阶段总是或多或少地存在虚假点迹。因此，有必要研究如何在数据处理阶段进一步消除杂波干扰。文中分别就数据
处理的预处理模块、相关滤波模块、雷达控制模块以及雷达显示控制提出了有效的方法。-Shipborne radars operate in a severe clutter environment．No matter what measures of clutter suppression are a—
dopted in signal processing，radar engineers discover there are more or less false plots in the stage of radar data processing．So it is
necessary,to research for anti—clutter methods in the stage of radar data processing．This paper proposes some effective methods in
the stage of data processing including echo pretreatment，correlation filter，radar control and radar display contro1．
