摘　　要：针对机载小雷达天线挂装姿态要求高的特点,给出了一套完整的雷达姿态测量、处理及精度检测方法。针对测量平面点存在异常值扰动拟合结果不稳定的问题,给出了一种鲁棒的平面拟合方法,通过解算获得可靠的平面参数估计值,从而提高姿态解算精度。该套标定方法已在小雷达天线挂装标定中获得成功应用,取得了很好的效果,可推广应用在其他武器系统安装标定任务中。A complete method of data measurement and processing and accuracy examination for small airborne radar is given,which is used to solve the high precise attitude measurement of airborne radar target mounted.The results of planar parameters estimation are not accurate by traditional plane fitting methods to point clouds,because the outliers are not considered.A robust method for fitting local plane of point clouds is presented.Reliable plane parameter estimation value is obtained by solving the solution,which can improve precision measurement.The method of data measurement and processing is good to apply to the measurement,which can be applied to other weapons target mounted.
