Abstract
A non-contact method for detecting and distinguishing a human and an animal based on IR-UWB bio-radar signals includes: step 1, transmitting a radar pulse to a target by a transmitting antenna of an IR-UWB bio-radar; and obtaining, by a receiving antenna of the IR-UWB bio-radar, a radar echo signal E(n,m) generated from the radar pulse reflected on the target; step 2: performing signal preprocessing on the radar echo signal E(n,m) obtained in step 1, to obtain a first energy signal E(l); step 3: removing a direct wave from E(l) obtained in step 2 to obtain a second energy signal E(l), and obtaining a maximum amplitude Eof E(l) and a position lcorresponding to the maximum amplitude in a slow time direction; step 4: calculating a peak-to-background ratio Vof E(l), calculating an average correlation coefficient r, and determining a type of the target through a target detection and distinction rule.
