Synthesis of Sparse Array with Sum and Difference Patterns under Minimum Element Spacing Control by Alternating Linear Programming Optimization
IEEE Antennas and Wireless Propagation Letters(2021)
摘要
A novel method based on alternating linear programming optimization is presented to synthesize sparse linear arrays with sum and difference patterns. This method can find the optimized element positions and excitations shared for both sum and difference patterns with accurate control of multiregion sidelobe distribution and difference pattern null slope. In addition, the constraints on the minimum...
