摘　　要：正交相关器能够检测低于噪声电平的信号,但在避免强干扰源产生错误方面仍存在局限性。利用相关检测和最小方差无畸变响应(minimum variance distortionless response)[1]波束形成算法相结合的方法,抑制非期望波达方向的干扰噪声,提高对弱信号检测能力。理论分析和仿真试验结果表明改进后的接收机对强干扰有一定的抑制力。Orthogonal correlator is capable ence. with the method of relatively detecting and terference from unrespected direction to enhance amination all indicate that the improved receiver of receiving the signal lower than noise,but it can not avoid strong interfer MVDR （minimum variance distortionless response）. It can restrain the in the ability of measuring weak signal. The theory analysis and emulational ex has great improvement in restraining strong interference.

关 键 词：相关正交器 最小方差无畸变响应 波束形成
