摘　　要：提出二维固态有源相控阵失效单元补偿的新方法 ,该方法基于失效单元矩形切割和线性规划方法。可适用于有源阵列多单元任意失效分布的实时补偿。在保证失效补偿后两主平面副瓣性能完全恢复的情况下 ,用线性规划方法对空间平均副瓣进行了优化。由于采用实数算法 ,仅需对非失效单元的幅度进行调整。A novel method of failure compensation for 2 D solid state active phased arrays is presented. Based on the failure element rectangular cut and linear programming, it is suitable for real time compensation of any multi elements failure distribution. In the case of maintaining the array two main plane side lobe equal to ideal ones, the array average side lobe level (AVSLL) is optimized by the linear programming. Due to the real algorithm, the array non failure element amplitude will be adjusted only. The theoretical analysis and simulated results show that this method is available in the practical engineering applications.
