主瓣可控的鲁棒自适应波束形成算法
Robust Adaptive Beam-Forming Algorithm with Controllable Main-Lobe
摘要
Abstract
Adaptive Beam-forming technology can effectively improve the SINR of array by receiving the desired signal and rejecting the interference,while traditional adaptive algorithms can not control the beam shape.In order to form a fixed width of the main-lobe,beam-forming problem is transformed into a weighted pattern synthesis problemby defining the weight function.The modified covariance matrix improves the robustness of the algorithm,and iterative FFT method is used to solve the resulting expression.The simulation results show the proposed method can control the width of the main-lobe and form a null in the direction of interference.关键词
