面向星间链路的机械加电扫相控阵天线指向权值算法

A Pointing Weight Algorithm for Inter-satellite Links Oriented Phased-array Antenna with Mechanical Structure and E-scan

为了实现“北斗”星间链路地面设备使用单相控阵天线与全空域的“北斗”导航卫星建链的目的,设计了一种面向导航卫星的机械加电扫相控阵天线装置。通过对其建立全空域分割模型,提出了基于机械扫描加电波束扫描复合跟踪的天线指向权值动态赋值算法。以某型号星间链路地面设备为基础,通过暗室试验对该装置指向权值赋值后的指向精度进行了测试,结果表明该方法切实可行。

In order to realize the establishing the links between the inter-satellite links management equipment and Beidou navigation satellites in the whole airspace by using the single-phase antenna,the phased-array antenna with mechanical structure is designed.By establishing whole airspace segmentation model,the pointing weight algorithm for the phased-array antenna with mechanical structure is proposed.On the basis of an inter-satellite links management equipment,the pointing accuracy of the device is tested in a microwave anechoic chamber and the results show that the pointing weight algorithm is feasible.
