摘要：

This paper presents a micro-motion detection based on coherent ultra-wide band pulse radar, in the context of improving the general imaging pipeline of through-the-wall radar. The proposed micro-motion detection principle is based on the measurement of the phase difference of the UWB carrier waveform between the transmitted and the received pulse signal. An experimental proof of concept of the proposed micro-motion capabilities is reported in this paper, with the detection of a 5mm woofer periodical micro-displacement, representing a displacement magnitude of lambda/10. A radar architecture is designed to implement the imaging pipeline in real time, with this micro-motion feature. It performs 100GHz sampling frequency with an equivalent time sampling. The acquisition refreshing period of 2ms covers all biological micro- movement speed ranges.
