Global Navigation Satellite System (GNSS) provides opportunities for passive radar applications. This paper reports progress in space-surface bistatic synthetic aperture radar (SS-BiSAR) using Beidou-2 as transmitters of opportunity and a fixed ground-based receiver. Experiment is described and the obtained SAR image is presented and interpreted in detail. Results show that BiSAR using beidou-2 as...
The distributed coherent aperture radar (DCAR) consisting of several cooperating small aperture radars and a control center is proposed to replace the traditional large aperture radar, which is more easily to transport and less expensive to build. In this paper, the constitution and workflow of DCAR are described at first. In the following, the estimation methods of coherent parameters are introduced...
