设计一个简单的GUI界面，对导入的音频文件进行时域特性分析。计算其时域波形、平均幅度、短时能量、短时过零率。对该音频文件进行加噪处理，分析其时域波形变化。设定一个固定时长，对该音频添加回声并保存为“*.wav”格式文件。 对音频文件的时域分析是对音频文件进行传输、降噪及其他再编辑的基础。其中短时能量可用作清浊音区分的标准和语音起始点的判断。短时过零率可用作判断有声段与无声段和从背景噪声中提取语音信号。 (Design a simple GUI interface that time domain characteristics analysis on import audio files.Calculate the average time domain waveform, amplitude, short-time energy and short-time zero crossing ratio.Add to deal with the noise of the audio files, analyze the changes in the time domain waveform.To set a fixed time, to add the audio echo and saved as a *. Wav format file. The time domain analysis of the audio file was transmitted to audio files, noise reduction and other editor again.The short-time energy voiced distinguish between standard and can be used as a clear voice starting point judgement.Short-time zero crossing ratio can be used as a judgment audio segment and silent segment and extract speech signal background noise.)

现在的雷达都是在多脉冲观测的基础上进行检 测的，多个脉冲积累后可以有效地提高信噪比，从 而改善雷达的检测能力。积累处理可以在包络检波 前完成，称为检波前积累或者中频积累。信号在中 频积累时要求信号间有严格的相位关系，也就是说 信号是相参的，所以也称为相参积累。此外，积累 过程可以在包络检波后完成，称为检波后积累或者 视频积累。由于信号在包络检波后失去了相位信息 而只保留了幅度信息，所以检波后积累处理就不需 要信号间有严格的相位关系，因此这种积累又称为 非相参积累。实现非相参积累的方法有很多，例如 抽头延迟线积累（FIR 积累）器和反馈积累器。 ()
