Fourth-Order Sparse Array Design From a Sum-Difference Co-Array Perspective

Abstract: Sparse arrays designed based on fourth-order difference co-array (DCA) can achieve significantly higher uniform degrees-of-freedom (uDOFs). However, most existing fourth-order sparse arrays ...

Simultaneous Synthesis of Sum-and-Difference Patterns for Planar Arrays With Common Weights and Minimum Dynamic Range Ratio via Sequential Convex Optimization Method

Abstract: Simultaneous synthesis of array sum-and-difference patterns (SDPs) with reduced dynamic range ratio (DRR) of element excitation weights is of great importance. In this communication, a novel ...
