中文摘要：

针对目前对多波束相控阵天线角跟踪性能测试研究较少的问题，首先分析了多波束相控阵天线的单脉冲和差测角方法，并对波束滑动、波束穿越及信号频率变化对角跟踪性能的影响进行了仿真分析。类比传统的雷达精度校飞试验，提出了基于飞艇的角跟踪性能测试方法，对角跟踪精度及误差范围进行测试，并利用STK软件实现了可视化。仿真分析表明，该方法可以实现对多波束相控阵天线角跟踪性能的评定并具有较高的工程应用价值。

英文摘要：

Aiming at the limited research of measurement of multi-beam phased array antennas’ angle tracking performance,the sum-difference monopulse angle measurement is firstly analyzed and the effects of beam sliding,beam crossing and change of signal frequency are simulated in this paper. Subsequently,compared to conventional radar calibration flight test,a novel measurement based on the airship for tracking performance which can test the tracking accuracy and error range is proposed,and visualization of the measurement is achieved through STK software. Numerical simulations demonstrate that the proposed method can accurately measure the performance of angle tracking and is suitable in engineering practice.
