Multirotor UAV-borne Repeat-Pass CSM-VideoSAR
2021
A 360-degree video synthetic aperture radar (VideoSAR) appears as an interactive observation capability to understand the dynamic scenarios. VideoSAR system mounted on an unmanned aerial vehicle (UAV) delivers a highly flexible and cost-effective approach. In this article, the UAV-borne repeat-pass circular stripmap (CSM) VideoSAR observation is formulated in format of video area overflown to enhance the wide-area surveillance capability. A completely 2-D interpolation-free polar format algorithm is employed, especially in terms of repeat-pass CSM-VideoSAR configuration. We conduct the repeat-pass CSM-VideoSAR experiments on multirotor UAV-borne system in the interests of imaging demonstration and promoting the inspirations on the related open issues.
