Radar network has important application in many fields, such as small target detection etc, especially for the case with wide baseline. Until now, the research to the 3-dimensional (3D) target localization accuracy using radar network is still a research focus in the radar community. In this paper, further research to the radar network with aerial and ground-based nodes is carried out, and the analytical...
Conventional space-time adaptive processing (STAP) is difficult to effectively suppress nonhomogeneous clutter in practical airborne phased array radar systems owing to the requirements of large independent and identically distributed training samples and the high complexity involved in the inversion of a high dimensional matrix. In order to improve the clutter suppression performance with a small...
A highly squint airborne SAR real-time imaging algorithm named the extended CS algorithm is introduced in the paper. Some important approximations of the classic CS algorithm are analyzed and the analyzed method is valuable for the selection of imaging algorithm for a SAR system. As the squint angle becomes larger, the approximation error will be unacceptable and the algorithm should be modified....
ln order to research imaging algorithm problems of space-borne bistatic SAR, it is necessary to simulate echo data of actual scene. On the basis of point target simulation, a method of simulating space-borne bistatic SAR raw echo data utilizing gray image data of airborne SAR is presented in this paper. First of all, gray data of airborne SAR image is added and averaged to compute different targets...
