本文提出了一种新的方法来构造适合于正交多波束接收器应用的稀疏天线阵列。首先将M×N元平面矩形阵列的功率方向图简化为正交布置的交叉乘法子阵。然后使用压缩传感(CS)方法重新分布这些阵列，以实现沿两个一维子阵列的阵列细化，以获得固定的定向波束投影。然后，实现了一种多波束综合方法，该方法允许有效的波束极大值以及多个隔行扫描的远场图案的零点布置。最后给出了数值算例，说明了该方法的实现。
This paper presents a novel approach to formulate an aggressively thinned sparse antenna array suitable for orthogonal multibeam receiver applications. The power patterns of M x N element planar rectangular array are first reduced to orthogonally placed cross multiplicative subarrays. These arrays are then redistributed using a compressive sensing (CS) approach in order to achieve array thinning along two 1-D subarrays for a fixed steered beam projection. A multibeam synthesis approach is then implemented which permits efficient beam maxima as well as a null placement of multiple interlaced far-field patterns. Numerical examples are presented to show the implementation of the proposed approach.
