In the paper the problem of the ground clutter rejection for airborne SAR is discussed. The features of space-time clutter filtering and clutter spectrum of airborne SAR imaging are analysed. It is pointed out that there exist some problems such as Doppler ambiguity and blind speed band expansion when STAP filtering is applied to the ground clutter cancellation. Aiming at the solving of difficulties...
For airborne ISAR imaging of ship targets at sea, both ship's three-dimensional rotation driven by waves in the sea surface and the relative tangential translational motion between the platform and the ship contribute to the imaging. At high sea-state and in long-range and low-altitude observation, the rotation component produced by the relative tangential motion between the radar and the ship is...
Inverse synthetic aperture radar (ISAR) has been highly exploited for target recognition due to its high resolution imaging capability. Scaling of the ISAR image is a necessary step to the reliable target recognition. Usually, the target motion is unknown. The amount of rotation during the observation cannot be determined, so it is difficult to perform the cross-range scaling. In this paper, a technique...
In airborne ISAR imaging of ship targets, the complexity of the ship's rotation relative to the radar line of sight (RLOS) increases the difficulty in achieving high quality ship images. When imaging from long distance, the rotation induced by the tangential motion between the radar and the ship can always be neglected. The images obtained by exploiting the ship's own sway are generally the ship side...
Inverse Synthetic Aperture Radar (ISAR) is used to image noncooperative moving targets such as aircrafts, ships and celestial objects. The target rotation relative to the radar is the source for obtaining cross-range resolution in ISAR imaging. In airborne ISAR imaging of ships, the composition of the relative motion is more complicated than in other cases. One component is produced by the relative...
