基于相控阵的全空域多目标测控天线分析

基于抛物面天线的测控系统,已经不能满足全空域内同时多目标测控的需求。针对单站全空域多目标测控中存在的问题,提出了基于球面相控阵的全空域多目标测控天线体制。比较了全空域多目标相控阵测控天线形式,在研究球面相控阵天线原理的基础上,对辐射单元及子阵布局进行了分析与设计,对波束合成后的天线方向图进行了仿真。结果表明:基于球面相控阵的全空域多目标测控天线能够有效解决未来全空域多目标同时测控的需求。

Analysis of Whole Airspace Multi-target TT&C Antenna Based on Phased Array

The TT&C system based on parabolic antenna can not satisfy the demand for multi-target TT&C in whole airspace. In order to solve the problems encountered in whole airspace and multi-target TT&C by single station,the antenna system based on spherical phased array for whole airspace and multi-target TT&C is proposed. Analysis and comparison the form of phased array antenna for whole airspace and multi-target TT&C, based on the analysis of the principle of spherical phased array, the radiation element and array layout are analyzed and designed, the antenna pattern of beam forming is simulated. Results shows that, the needs of future multi-target TT&C in whole airspace can be met effectively by whole airspace and multi-target TT&C antenna based on spherical phased array.
