摘要
Mini-SAR技术是目前SAR领域一个新兴的重要研究方向,但目前投入实用的成像算法很少。针对Mini-SAR的成像原理,给出了一种新的投入实用的极坐标成像算法,通过对该算法优缺点的研究,分析了Mini-SAR成像场景、分辨率及作用距离三者之间的关系,讨论了该算法对成像场景尺寸的限制要求,明确了算法的适用条件;最后利用某型Mini-SAR实际复数图像数据验证了该算法的正确性。研究结论对国内小型SAR的研制具有一定参考价值。
Mini synthetic aperture radar (Mini-SAR) technique has been a rising and more important research direction in the field of SAR technology for Military applications. But few related technology has been reported from now on. New and applied polar format arithmetic for MinbSAR has been discussed. A detail analysis of relations among imaging scene, resolution and range have been represented, and the applicability of the arithmetic has been proposed. Finally, the validity of the analysis has been verified with true Mini-SAR image data. Some valuable suggestions have been given for the related Mini-SAR research.
