为解决船载雷达在海上动态情况下雷达光轴与机械轴之间的偏差无法准确标校的问题，提出了采用标校电视反向法瞄船桅光标，在海上动态条件下标校雷达光机偏差的新方法，并分析了该方法的可能误差源，得出改正角误差是反向法光机偏差标校的最大误差源，给出了减少或避免改正角误差的三个解决方法，即智能选择法﹑相对比较法和最小二乘法，利用相对比较法对反向法光机偏差标校数据进行误差修正，标校精度优于10"。试验结果表明，该方法解决了近距离改正角误差较大的技术难题，提高了标校精度，且该方法操作性强，在船载雷达上有较高的实用价值。

In order to solve the problem that the deviation between the ship-borne radar optical axis and mechanical axis can not be calibrated accurately in dynamic sea condition,this paper proposes a new meth-od to calibrate the ship-borne radar's optical-mechanical axis non-parallelism by calibrating TV reverse method aiming calibration target on mast in dynamic sea condition,analyzes possible error sources of the method,confirms that the parallax error is the largest error source of the reverse optical-mechanical axis non-parallelism calibration method and gives three solutions to decrease or avoid the parallax error,namely intelligent selection method,comparative method and least square method. The comparative method is used to correct calibration data and the calibration accuracy is better than 10". Tests show that the method im-proves the calibration accuracy by solving the technical problem of how to correct parallax error at short range,features high operability and high accuracy,and has high practical value for ship-borne radars.
