Abstract: Through-wall detecting radar used as a new kind of radar whose detecting target can be divided into moving and static state human body has extensive applied foreground in domain of searching and rescuing in the disaster,anti-terrorism and etc, so it causes people’s numerous concerns. It is more difficult to locate static human body compare to moving human body,so the emphasis discussion of this text is to detecting and locating static human target.The whole signal processing process of locating static human target based on through wall detecting radar was described in detail,which including obtaining raw radar data,pre-processing radar echo signal,extracting and distinguishing characteristic signal of static human body,locating the static human target,especially in extracting characteristic signal of static human body,it obtained well effect by using the modern signal processing method of Siguar Value Decomposition and adaptive Least Mean Square whose advantage and disadvabtage was analyzed and compared in this text, at last the locating experiment results of static human target are present which validate the effectiveness and feasibility of the signal processing method described in this paper.
