Abstract

An effective two-dimensional polar format algorithm based on the circular sampling theorem is implemented and tested. The algorithm interpolates samples from a polar to a rectangular raster for the purpose of focusing ISAR imager. The imagery are generated from samples collected in the frequency space utilizing a uniform polar set of coordinates. An example of an extended target is offered to show the versatility of the algorithm. In addition, a point target model is used to test its effectiveness. The distortion introduced by interpolation is calculated and compared to errors introduced by two standard interpolation techniques. Experimental data provided by the Pacific Missile Test Center was used to test the proposed algorithm.
