ABSTRACT:
Systems and methods for measuring RCS patterns of large targets in a compact target range having limited size. The present invention utilizes a compact range whose sweet spot (corresponding to the imaged area of the target) is much smaller than the target size. Inverse synthetic array radar (ISAR) images of successive sections of the target are registered to form a composite image of the whole target. The image is then Fourier transformed to generate an RCS value of the full target. This procedure is repeated for successive measurement angles, an RCS versus .theta. plot is generated corresponding to the RCS pattern of the target. The multiple images may be generated by translating the target and computing RCS plots of the target by combining the multiple images produced during translation, or generating the the multiple images by moving feeds or using multiple feeds of the ISAR system.
