Backward propagation image reconstruction techniques for bistatic synthetic-aperture radar imaging systems with circular-aperture configurations

摘要

Backward propagation has been an effective algorithm for high-resolution image formation in many applications. In the past, the implementation of this technique has been limited to the configurations of linear and planar aperture arrays. This paper presents the conversion to the circular-aperture configurations and demonstrates the capability of the algorithm in monostatic and bistatic imaging modes.
