基于中大型雷达设备可以方便地跟踪中低轨空间目标的特点,提出了通过跟踪精轨卫星标校雷达设备的原理和方法,分析了该方法相比传统雷达角度标校方法的优点,给出了方位/ 俯仰型雷达天线利用跟踪精轨卫星进行角度标校的误差修正模型、数据采集方法、标校参数的最小二乘拟合算法,并结合某雷达的实际标校结果,验证了该标校方法在实际工程中的可行性。

Radar with large aperture antenna is capable of tracking LEO and MEO satellites, based which radar calibration principle and method by tracking satellites with precise orbit parameters is proposed. Advantage of the method over those traditional radar angle calibration methods is analyzed. The Error correction model, data collection method and the least-square fitting algorithm of the angle calibration parameters are given. Then the actual radar calibration results is used to verify the feasibility of the method in practical engineering.
