摘要
基于空间功率合成的分布式卫星对抗系统需要对卫星通道参数进行测量跟踪。根据卫星漂移特点,建立了卫星通道参数测量跟踪模型,提出了一种基于卡尔曼滤波的测量跟踪方法。仿真结果表明,该方法可以有效跟踪卫星通道相对时延和相位的变化。
The distributed satellite countermeasure system based on spatial power-combination has to measure and track the parameter of satellite channel. According to the characteristics of satellite excursion, a measuring and tracking model is set up of satellite channel parameter and a measuring and tracking method is proposed based on Kalman filtering. Simulation results show that this method can track delay difference and phase difference effectively.
