抗阵列流形误差的稳健低旁瓣波束优化设计
Optimal Design of Robust Low Sidelobe Beam Against Array Manifold Error
摘要
Abstract
In this paper,a robust beam optimization method for hydrophone array is studied. The influence of array manifold error on the performance of beamformer is analyzed. Two robust low sidelobe beamforming methods against array manifold error are designed:L1 norm criterion method( L1 method)and L2 norm criterion method( L2 method). In the case of different element po-sition errors,the two methods are simulated and analyzed. Compared with the ideal minimum sidelobe(SCOP)beamforming optimi-zation method,the L1 method and L2 method have better robustness,which verifies the correctness and feasibility of the robust low sidelobe beamforming method against array manifold error.关键词
