To fully utilize the character of the bioradar echo signal, autocorrelation analysis, spectral estimation methods and time-frequency analysis are presented in this paper. These methods are employed to deal with no one, single people and multi-people

频域均衡算法的总结，对经过时间捕获的导的时域信号进行信道估计之后，得到其信道频域响应，进而消去每一帧信号的噪声干扰还原的到原始信号。-Frequency domain equalization algorithm, the time-trapped time domain signal channel estimation, the channel frequency domain response, and then eliminate the noise of each frame of t
