摘要
介绍了星载滑动聚束合成孔径雷达(SAR)的成像原理,构造了滑动聚束SAR的方位模糊度计算模型,并分析了其距离模糊度计算模型。系统设计及模糊特性仿真结果表明:模型可用于SAR系统参数优化设计。
The imaging characteristics of sliding spotlight synthetic aperture radar(SAR) were introduced in this paper.The azimuth ambiguity calculation model of sliding spotlight mode SAR was constructed.The range ambiguity calculation model was analyzed.The results of corresponding system design and ambiguities simulation showed that this model could be used for parameter optimization of SAR system.
