为了达到抑制失效阵列天线旁瓣显著抬升的目的,对失效后的阵列天线进行波束重构显得尤为重要。首先给出有源天线系统波束重构的基本思想,并详细给出粒子群算法实现的基本原理和步骤;然后提出一种新的失效信号重构优化算法,算法实现复杂度低,能够在系统中实时计算相位加权值,并满足系统性能要求。仿真结果表明:新的有源天线系统容灾算法可以有效地降低天线阵子单元损坏对有源天线性能影响,同时算法实现复杂度低。

This paper firstly gives the basic idea of beam reconstruction of active antenna system, and gives the basic principle and steps of particle swarm optimization. Then a new failure signal reconstruction optimization algorithm is proposed. The algorithm has low complexity and can be implemented in the system. The phase weights are calculated in real time and meet system performance requirements. The simulation results show that the new disaster recovery algorithm for active antenna system can effectively reduce the impact of antenna element damage on the performance of active antenna, and the complexity of algorithm implementation is low.
