为确保雷达系统的测量精度，给出了一种用于标校雷达动态跟踪过程中系统误差的工程实现方法--卫星标校法。该方法通过观测卫星轨迹，将量测值与真实星历值比对，通过最优化解法标定雷达的系统误差。考虑雷达结构特点导致的误差和大气折射误差修正后的残余误差，建立了卫星标校的系统误差模型。最后，采用实测数据验证了该误差模型的可行性与可靠性。该方法在标校过程中不受人为、天气等因素影响，可以适应雷达的动态技术状态。

To guarantee the measurement precision of radar system, this paper presents an engineering implementation method, named satellite calibration, used for calibrating the system error in the course of radar dynamic tracking. This method contrasts the measurement value to the real ephemeris value by observing the satellite track, and calibrate the radar’s system errors by using the optimal solution. Considering that the errors caused by the features of radar configuration and the residual errors after correction of atmosphere refraction errors, the author sets up a system error model for satellite calibration, and finally proves the feasibility and reliability of this proposed error model using the test data. As this method is not affected by some factitious and weather factors, it can be also adapted to radar’s dynamic technical state.
