Stripmap mode, spotlight mode, and sliding spotlight mode are the three SAR working modes. We present a comprehensive and systematic study for demonstrating differences among the three imaging modes in imaging geometry model, azimuth frequency course, range cell migration, antenna scanning velocity, azimuth mapping strip width, azimuth resolution, and echo equations. Simulation results further confirm the differences among the three modes. By comparing these three modes, we conclude that stripmap SAR and spotlight SAR can be considered as the two special cases of sliding spotlight SAR.
Key words： frequency course; range cell migration; sliding spotlight
