Abstract :
Life detection radar is a sort of initiative life detection equipment with extensive uses. A colored Gaussian noise model and a harmonic signal are proposed by analyzing the experimental data in this paper. The capability compare is done between wavelet filter and FIR filter about the suppression of clutter and detection of signals, the experimental signals have characters of low-frequency, semi-periods, and low SNR.. The results show the delay of wavelet filter is shorter than FIR filter and SNR is improved, so new algorithm is much validity and stability.
