摘　　要：阵列天线的稀布优化是近年来的研究热点,该技术在保证方向图性能不变的情况下,减少阵元数目,重新规划阵列中阵元的排布.本文使用酉矩阵束算法对全波仿真阵列进行稀布优化,得到稀布后阵列的阵元数目、阵元位置和阵元激励等信息,并将稀布阵的阵元数目、位置和激励等信息带入到HFSS里,对稀布阵进行仿真建模,将稀布阵列和原阵列的方向图、阵元位置、阵元激励等信息进行比较,验证算法的实用性和精确性.The sparse distribution optimization of array antenna is a research hotspot in recent years.This technique can reduce the number of elements and rearrange the elements in the array.Firstly,the algorithm principle of unitary matrix beam algorithm is introduced;secondly,the antenna unit and antenna array are modeled and simulated in HFSS software;secondly,the sparse array is optimized by unitary matrix beam algorithm;finally,the sparse array is modeled and simulated in HFSS,and compared with the simulation results of the original array,the effectiveness and practicability of the algorithm are verified.
