Theoretical Study on Bistatic Circular SAR Image Reconstruction
Takuma Watanabe (FSI) SANE2023-5
Abstract (in Japanese) (See Japanese page) 
(in English) Circular synthetic aperture radar (CSAR) is a type of imaging radar in which the radar-carrying platform moves along a circular path enclosing the target to be imaged; the radar antenna transmits an electromagnetic wave toward the target, and the scattered wave is recorded during the movement. The major advantages of CSAR compared to conventional SAR using a linear scanning path are that CSAR can achieve a higher resolution and reduce the shadowing effect of the radar by irradiating the target from all azimuth angles by moving along the circular path. In this study, we develop an image reconstruction algorithm for a bistatic CSAR, in which the transmitting and receiving antennas are located at different positions. Moreover, we derive a correction factor for the bistatic CSAR, which is incorporated in the integral transformation used to realize the image reconstruction. The proposed algorithm is validated using a simple numerical simulation based on a point-scatterer model.
