摘　　要：高度是三坐标雷达的重要参数,在实际使用中器件损坏等原因经常导致高度精度出现偏差,特别是在无人值守或少人值守的雷达站检修措施很难得到落实。为了解决测高精度出现偏差时检修措施落实难的问题,提出了根据目标探测的数据进行误差原因分析以及针对性的软件修正措施,达到了提高探测精度的目的,并对修正方法进行了评价,显示了修正方法的优越性和不足。Height is an important parameter of 3D radar.In pratical,device damage and other factors often lead to deviation,especially in the unattended or less people on duty radar maintenance,where maintenance measures is difficult to be implemented.To solve the problem,a solution of software corrective measures is proposed which is based on analysising the error reason of target detection data.The solution achieves the purpose of improving the detection accuracy.The advantages and disadvantages of the solution are given.
