this project focuses on the development of a sophisticated SAR simulation capable of generating realistic SAR images for SAR Automatic Target Recognition (ATR). By refining the simulation for complex two-dimensional targets and simple three-dimensional targets, we can accurately capture the reflectivity properties of the targets and generate SAR images that closely resemble the originals. Through the utilization of the Range Doppler Algorithm (RDA), the resulting SAR images are further processed to enhance their resolution and enable precise target recognition. The successful implementation of this project holds great potential for various fields, including surveillance, remote sensing, military applications, and disaster management.
