Abstract :
This paper presents the outcome of a staring spotlight experiment with TerraSAR-X for considerably enhanced azimuth resolution. The commanding is discussed in terms of calculation of the azimuth steering angle. The performance estimation results are given for TerraSAR-X parameters and a steering angle range from -2.2° to +2.2°. The first TerraSAR-X staring spotlight images are presented.
