摘　　要：提出了一种校正受检雷达精度的新方法。该方法利用搭载具有数据存储功能的GPS的小型无人机作为受检雷达的跟踪目标,通过把雷达录取终端时间与GPS时间对齐,并结合差分GPS定位技术对受检雷达观测到的无人机数据进行精度分析,初步得到了受检雷达的精度。根据分析结果对受检雷达进一步校正,使受检雷达满足精度指标要求。A new approach of calibrating the accuracy of the radar tested is proposed. The miniature pilotless aircraft with the GPS having the function of data storage is treated as the target tracked by the radar tested, and the accuracy of the data detected by the radar, which makes the time of the terminal extractor and the GPS synchronous, is analyzed in combination with the difference GPS positioning technology. The accuracy of the radar is obtained initially and then further calibrated according to the results of the analysis to make the radar meet the requirements of the accuracy indexes.
