Moving Target Shadow Detection and Tracking based on THz Video-SAR

Terahertz video SAR can perform high-resolution imaging of targets in a short period of time, which is conducive to detection and tracking of ground moving targets. A new method is proposed in this paper for moving target shadow detection and tracking, which is verified on terahertz band data for the first time. According to the specific characteristics of terahertz video SAR images, this method is realized by change detection through background modeling and image difference. In the experiment, the effectiveness of proposed method is verified by the terahertz videoSAR images.
