摘　　要：宽带相控阵雷达通道均衡一般采用宽带信号测量通道失配特性,该方法需要宽带信号作为测试源输入,并且整个系统链路设计复杂,精细度要求高。本文利用离散单载频信号测量通道频响特性,然后基于离散频响拟合整个带宽内频响特性,最终获得宽带通道均衡系数。该方法可简化宽带相控阵雷达系统设计。Channel mismatch is usually measured using wideband signal in wideband phased array radar.But wideband signal is used as test source for the method,and data link is complex and need high fineness. In this paper,one method of measuring channel frequency response characteristics is presented using single-carrier frequency signal. And then wideband channel frequency response can be get by fitting single-carrier frequency response,finally filter coefficients of channel equalization is solved. The design of phased array radar can be simplified based on the proposed method.
