摘要
基于信号子空间的基本原理,结合模拟退火算法,提出了一种精确估计天线阵互耦系数的方法。该方法的优点在于使用信号源少,稳定性好,即使在雷达工作、并且存在其它未知信号时,也能准确估计出天线阵的互耦系数。大量的计算机模拟结果证实了其有效性。
For the arrays of high frequency ground wave radar, a method with two signals to estimate the mutual coupling coefficient of arrays were brought out. which was based on the principle of signal subspace and utilizing the simulated annealing algorithm. A great deal of compute experiment proves the efficacy of this method.
