摘　　要：针对当前星载相控阵宽频带、轻量化需求和天线阵列超密集布阵的特点,研究大规模平面稀疏天线阵列能够有效简化通道设计、降低散热难度,同时具有一定的副瓣抑制效果。首先介绍天线阵列稀疏优化技术的基本原理;其次综述几种常用的大规模平面阵列稀疏优化技术,包括确定性稀疏方法、随机性稀疏方法和混合稀疏优化方法;最后总结这几类阵列稀疏优化技术的优缺点,并展望其未来发展方向。According to the current broadband and lightweight requirements of spaceborne phased array and the characteristics of ultra dense antenna array,the research on large-scale planar sparse antenna array can effectively simplify the channel design,reduce the difficulty of heat dissipation,and have a certain sidelobe suppression effect.Firstly,this paper introduces the basic principle of antenna array sparse optimization technology;Then several commonly used sparse optimization techniques for large-scale planar arrays are reviewed,including deterministic sparse methods,stochastic sparse methods and hybrid sparse optimization methods;Finally,the advantages and disadvantages of these sparse array optimization techniques are summarized,and their future development is prospected.
