Abstract:

Based on the study of adaptive algorithm based on the formation of anti-jamming algorithm beam LCMV algorithm,this paper proposes a processing beam forming algorithm based on sparse processing.Small step traversal is applied to the angle of incidence between the interference and the target,while long stride traverse to other angles,greatly reducing the computing in pattern formation.Simulation results verify its correctness and show that operational efficiency is improved while meeting all performance requirements.
