Abstract: In this paper survey of different signal processing algorithms for detection of live human behind the wall or barrier is discussed. For all life detection systems, it is difficult to detect the weak life signals from strong echo waves of background noise. The detection signals due to respiratory movement are always weak so that they are easy to be buried by noise, which will increase detection difficulty and even reduce the detection accuracy. Many clutters and noises of system influence seriously. For proper detection of life signals behind wall or barrier, system performance is most important. The performance of system mainly depends upon signal processing algorithm or technique.

Keywords: Life Detection, Signal Processing, Radar Echo, Clutter.
