Abstract
For the purpose of improving the utilization rate and detection capability of space surveillance radar, a meaningful Implementation of bi-static inverse synthetic aperture radar (ISAR) is proposed. Bi-static ISAR imaging is helpful to extract the shape and size information of objects from different perspectives. The ability of anti-jamming, anti-stealthy and target recognition will be increased owing to bi-static imaging. The particularity of bi-static ISAR imaging is analyzed, followed by imaging simulation. An effective bi-static ISAR system is constructed including a wideband mono-static radar, a wideband receiver, and an accessional facility which performs signal acquisition, storage and processing. Outfield experiments of space objects observation were carried out and two-dimensional bi-static ISAR images were obtained successfully.
