摘　　要：舰载雷达鉴定试验是雷达试验的重要部分。为了对雷达的性能作出置信度高的评判,数据处理是关键。只有因素考虑全面、模型建立正确,才能获得高精度的真值数据,进而实现对雷达的可靠评判。分析了数据处理的流程和关键环节,针对空间变换、舰体运动参数补偿、时间校准3个关键问题进行建模,并用实例计算结果验证了模型的可行性和有效性。The Shipborne radar evaluation test is an important part of the radar test.Data processing is the key to making high-confidence judgments on radar performance.Only when the data processing factors are comprehensive and the model is established correctly,the high-precision data can be obtained,the reliable evaluation of radar can be realized.The process and key links of data processing are analyzed.Three key problems of space variation,motion compensation of ship and time calibration are modeled,the feasibility and effectiveness of the model are verified by the calculation results of examples.
