针对Ka频段低轨遥感卫星数据接收系统跟踪性能测试中的问题，提出了一种新的测试方法。利用设计的Ka频段低轨卫星动态目标模拟数据，采用转动第三轴跟踪标校塔Ka频段信标的方式模拟动态目标的跟踪，在研制的原型系统中开展了接收系统跟踪性能的测试验证。该测试方法可为Ka频段低轨卫星数据接收系统跟踪性能的测试验收提供参考。

To solve the problems in the tracking performance test of Ka-band Low Earth Orbit( LEO) re-mote sensing satellite data receiving system,a new method is proposed. Simulation data is generated by u-sing Ka-band LEO satellite,and dynamic target tracking is simulated with the method of tracking Ka-band beacon on the calibration tower by rotating the third axis of antenna. A verification test on tracking per-formance of receiving system is carried out in the developed prototype system. The proposed method pro-vides a reference for acceptance test for Ka-band LEO satellite data receiving system.
