Analysis of the Imaging Projection Plane for Ship Target With Spaceborne Radar.

For the convenience of target feature extraction, classification, and recognition, it is necessary to research the imaging projection plane (IPP) of spaceborne hybrid synthetic aperture radar (SAR) and inverse SAR (ISAR) imaging results of ship target on the sea surface. In this article, a novel analysis approach of IPP is proposed, by which the expressions of IPPs can be derived under the condition of different rotation and ship’s bow directions. Then, the representation of radar image can be predicted in advance, i.e., top view, side view, or hybrid view of the target. Finally, the simulated and real measured data are processed to generate the radar images to verify the correctness of conclusions in this article. [ABSTRACT FROM AUTHOR]
