Abstract:

The experimental research of micro-Doppler effect in digital terrestrial multimedia broadcasting (DTMB) based passive radar is presented by using the newlydeveloped multichannel passive radar system of Wuhan University. Firstly, the passive radar micro-motion model is established. Secondly, the key techniques in signal processing are briefly discussed. Finally, the experimental progress is highlighted, including system introduction, illustration and analysis of typical experimental results of micro-Doppler effect, which proves the technical feasibility of using DTMB for micro-Doppler effect detection.
