摘　　要：雷达接收通道间的幅相不一致与通道带内频率特性失配对DBF(数字波束形成)的副瓣电平及输出信噪比有很大影响。本文介绍了一种基于最小二乘原理的自适应通道均衡方法,并对不同的迭代方法作了比较与仿真实验。Unbalance of amplitude phase in radar receiving channels and mismatch of frequency characteristic within channel band may affect the sidelobe level and output signal-to-noise （SN） ratio of digital beam forming （DBF） seriously. The adaptive channel equivalent method based on principle of least square is presented, and different iterative methods are compared and its simulation experiment is carried out.
