摘要
舰炮火控雷达试验特别是科研性试验期间,需要对雷达的测距精度进行分析,找出影响雷达测距精度的关键因素,进行数据标定或修正。引起雷达测距误差的因素较多,针对多路径误差、距离闪烁、大气折射、热噪声误差等关键因素进行理论分析,并结合工程实践给出了一些实测数据和测试结果,最后提出减小距离测量误差或误差修正的方法。
Range accuracy analysis is very important for naval gun radar test,especially for scientific research test.we must analyze key factors that have effect on range accuracy,and then take measures to correct it.In this paper,the error factors including multipath error,range glint error,atmosphere refraction error,thermal noise error are discussed,based on engineering application,some experimental results are also presented.in the end,error correction method used to reduce range errors a are introduced.
