Human tracking using range and velocity measurements by multistatic radar

Multistatic radar system has a great potential for human detection and tracking for its fine localization precision, wide coverage and good observability. Traditional human detection and tracking are performed on the one dimensional (1-D) range profile. If targets are close or overlapped in range, it is difficult to distinguish these targets and obtain the measurements for target tracking. It can lead to the discontinuities of the human trajectories. As velocity provides another dimension to distinguish targets, in this paper, we propose to detect the targets on the range-Doppler (RD) image. Target localization and tracking is based on both range and velocity measurements. The performance of the human tracking method is verified by the experimental data in the foliage-penetration environment.
