Advances in Bistatic Inverse Synthetic Aperture Radar

Bistatic geometries are enabled in scenarios where multiple separated transmitters and receivers are employed as well as when illuminators of opportunity are exploited. Bistatic Inverse Synthetic Aperture Radar (B-ISAR) becomes the radar imaging tool for obtaining non-cooperative target images in arbitrary bistatic configurations. Theoretical aspects and real data experiments have been conducted in recent years that have proven the effectiveness of B-ISAR. A review of both theory and results is provided in this paper and new perspectives are indicated.
