SARrawSim: Synthetic Aperture Radar Raw Data Simulator

This manuscript introduces a synthetic aperture radar (SAR) simulator and presents the application of the Range-Doppler Algorithm (RDA) to process the simulated SAR data. The simulator efficiently generates raw data by considering various radar parameters and point targets within a specified probing area. The RDA is used to perform range focusing, range cell migration correction (RCMC), and azimuth focusing on the raw data. The resulting SAR image is presented as an outcome of this process, providing valuable insights into SAR system design and algorithm validation.
