摘要
介绍了模拟退火法的基本原理。该方法具有全局寻优能力,在阵列天线综合中主要有以下3方面的应用:对均匀阵列的电流分布,对非均匀阵列的阵元位置及电流分布进行优化,对阵列进行稀疏化。仿真结果表明,模拟退火法是一种有效的阵列天线优化综合方法。
The basic rationale of SA(simulated annealing) is presented.Being capable of searching optimum results globally,it could be utilized to optimize the current distribution for equally spaced arrays,and to optimize the position of elements as well as the current distribution for unequally spaced arrays.Furthermore,it can also be used to thin full arrays.Results obtained by simulation show that SA is an effective optimization algorithm for array antenna synthesis.
