摘　　要：波束空间部分自适应处理是一种重要的降维方法,本文进一步从理论上分析了波束空间部分自适应处理的特点,以及辅助波束的选取、波束空间中干扰信号子空间的降维等关键问题,并提出了有效方案抑制密集型干扰,数值计算结果验证了其有效性。Partially andaptive processing in beam-space is an important method of reducing rank adaptive beamforming. The Characteristics of partially adaptive processing, the choice of auxiliary beams and reducing rank of interference signal subspace via per-beamforming are analyzed theoretically. An effective approach is proposed for the suppression of concentrated jammers, which is confirmed by numerical analysis.
