摘要
针对阵列误差存在时经典(Capon)波束形成算法的性能严重恶化问题,介绍了均匀圆阵阵列流型下的Capon波束形成算法,对阵列天线各阵元间的幅度误差、相位误差、水平位置误差和垂直位置误差进行了数学建模,仿真分析了各种阵列误差对Capon波束形成算法的影响,并给出了该影响的量化分析结果,从而对该算法工程实现时的指标确定提供依据。
To solve the problem of performance degrading effect of Capon beamforming algorithms when array error exists,a Capon algorithm under UCA was introduced. Then the mathematical model of array amplitude error,phase error,and position error was set up. Next the impact of the array error was simulated. Finally, the analysis results of its impact were given, which is useful for identification of specific parameters for engineering realization of the algorithm.
