Algorithm for the Latitude and Longitude of Point Targets in SAR the Imaging Scenario

为了及时对发现的点目标进行定位,适用于未来战争战场信息获取和快速反应的要求,本文针对SAR在正侧视和小斜视情况下的成像算法提出了机载SAR成像场景中的点目标经纬度的计算方法,使得我们能第一时间在SAR图像上根据所知参数计算出所需点目标的经纬度,并就该方法的精确性进行参数估计和试验研究,验证了其有效性。

In order to locate the point target found timely and satisfy the need to obtain information and respond quickly, this paper proposes an algorithm for the latitude and longitude of point targets so that given the known parameters, the latitude and longitude of a point target can be calculated on the SAR image at the earliest possible time. This paper also offers parametric estimation of and experimental research on the precision of the algorithm.
