A New Method of Cluster Optimization Design for Scanned Pattern Inerferometric Radar

摘要

To deal with the contravention between the reversibility of the point spread function of scanned pattern interferometric radar and the improvement of the azimuth resolution of the radar system, the paper presents a new method of cluster optimization design. The method bases on the variability of the maximum spatial frequency number of the theoretical formula of the array factor. By selecting an appropriate maximum spatial frequency number, we get a new aperture array. The array designed by this method not only can get the desirable azimuth resolution but also can guarantee the reversibility of the point spread function. Simulations validate the correctness of the method. At last, we also discuss the applicability of the method.
