摘要：
This paper analysis the signal detection method for life based on the theory of Doppler, and suggests that the characteristics of life signals and clutters could be achieved by analyzing the model of the life signals and clutters. The paper make the analysis on actually measured life radar echoed signals, focusing on the processing of digital filter and the echoed signals got after time-frequency transition. In the last, the paper discusses the ultra wideband theory and the characteristics of ultra-wideband radar signals and establishes the body detection model based on the theory study according to the characteristics of the ultra-wideband radar target. The echoed signals analyzed in this paper are obtained under the breath inhaling condition and contrasted by the quoted references, proving the validity and reliability of high resolution lidar range image of ultra-wideband radar target signal on life detection.
