Time-Domain Spaceborne SAR Point Target Echo Simulation

1. This program implements a time-domain spaceborne SAR point target echo simulation developed during my initial SAR studies, featuring satellite orbit modeling, coordinate system transformations for slant range calculation, SAR echo computation models, and basic SAR imaging algorithms, designed to assist beginners. 2. Reference materials include "Satellite Orbit Attitude Dynamics and Control" and "Wei Zhongquan: Synthetic Aperture Radar Satellite".
