摘要
研究了用自适应波束形成技术实现不规则阵列的方向图综合问题,改进了应用于方向图综合的迭代线性约束最小二乘方法,改进后的算法提高了数值稳定性和对随机稀疏阵的适应性。对特定的阵列如果指定的理想方向图无法达到,该算法可以获得最好的逼近。仿真结果验证了算法的性能。
The pattern synthesis algorithm for arbitrary arrays using adaptive beamforming method is discussed. An improved iterative linear constraints least square algorithm is presented. The new algorithm exhibits numerical robust and can be used with random sparse arrays. The algorithm finds the best attainable pattem with the given array if the pattern specifications cannot be met. Numerical examples are presented to illustrate the performance of the algorithm.
