摘要/Abstract

摘要： 摘要：提出一种改进的最小方差无畸变响应（MVDR）波束形成方法，通过调节波束形成的权向量设计中的增强因子来改善其方位分辨力，并且不以牺牲信号与干扰+噪声比增益为代价.仿真结果表明，所提出的方法可以有效改善MVDR波束形成的方位分辨力，且不损失MVDR波束形成的信号与干扰+噪声比增益.

关键词: 最小方差无畸变响应, 波束形成, 方位分辨力

Abstract: Abstract： An approach was proposed to improve the minimum variance distortionless response (MVDR) beamforming bearing resolution by designing an enhancement factor in its weight vector which is known to be a principal factor in resolution improvement under a high signaltonoise ratio (SNR) condition. This method can provide improved bearing resolution not at the expense of the signaltonoise plus interference ratio gain. The simulation results show that this method can effectively improve the MVDR beamforming bearing resolution without losing the signaltonoise plus interference ratio gain.

Key words: Key words： minimum variance distortionless response (MVDR), beamforming (BF), bearing resolution
