Abstract :
The airborne system PAMIR is able to acquire inverse synthetic aperture radar (ISAR) data for imaging of ground moving vehicles with very high resolution. The processing sequence contains both steps specifically developed for PAMIR and universal steps. The paper presents the image generation process based on PAMIR data of moving vehicles, which were recorded in spotlight mode. Target motion information is gained in different stages by range-Doppler tracking and a Kalman filter based approach incorporating a road map.
