Accurate two-dimensional imaging of a human body in motion using multiple ultra-wideband Doppler radar systems in a multipath environment

摘要

This paper presents a method of imaging a two-dimensional section of a walking person using multiple ultra-wideband Doppler radar systems. By exploiting multipath echoes, we can increase the effective number of radar systems virtually. Although each simple radar system consists of only two receivers, different line-of-sight velocities allow target positions to be separated and located. The data obtained using the multiple radar systems are integrated using DBSCAN clustering and a target tracking algorithm. Through realistic simulations, we demonstrate the remarkable imaging performance of the proposed method in depicting a clear outline of a human target.
