A review of sparse design methods for large-scale planar arrays

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.
