摘　　要：本文分析了超宽带单脉冲阵列馈源波未形成网络的幅一相关系。给阵列的各独立单元按要求的幅度比和相位关系进行馈电，从而形成单脉冲自跟踪和、差波瓣。该网络能实现左、右旋圆极化，体现了一种巧妙的设计思路，应用于超宽带接收，使用特别灵活方便。同时给出了组成框图和性能测试结果。An amplitude-phase relation of beam forming network in feed of ultra-wide-bandmonopulse antenna array is analyzed. The elements of the array, fed according to the desiredrelation of amplitude ratio and amplitude-phase provide a monopulse tracing 2-mode and △-modelobe pattern. The design of the network with left-hand or right-hand circular polarizationproperties is clever. lt is flexible in the application of ultra-wide-band receiver.The block diagramof the netwok and measured results are given.
