阵列有源天线单元失效的影响与补偿 总被引:1,自引:0,他引:1
首先分析了阵列天线因单元(或单元群)失效引起的副瓣恶化和增益损失,然后用BFGS最优化算法对失效单元(或单元群)附近部分正常单元的幅相进行适当调整。结果表明,这种调整对由于单元失效引起的副瓣电平恶化有较好的补偿效果。 相似文献

Based on the integral equation formulations and the moment method, a novel closed-form solution for analyzing the mutual coupling effect between the cylindrical comformal rectangular microstrip patch antennas is presented. By using this algorithm, the dements of the impedance matrix and exciting vector are cast into closed-forms, thus the computational efficiency is improved dramatically. Numerical results are presented to verify the validity and reliability of the algorithm. 相似文献
