| 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.

| Abstract: | Unbalance of amplitude phase in radar receiving channels and mismatch of frequency characteristic within channel band may affect the sidelobc 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. |
