一种中频雷达模拟器的设计

Design of One Radar Intermediate Frequency Simulator

摘要:

设计出了一种中频雷达模拟器的硬件,阐述了该模拟器总体组成和工作过程,以及各部分的组成和工作原理。该模拟器可以产生单脉冲体制下的一组固定目标的和、差模拟中频回波信号和动目标和、差模拟中频回波信号；可以在联机或独立2种工作状态下,产生常规脉冲、线性调频脉冲等多种雷达中频回波。该模拟器适用于相控阵雷达等多种新体制跟踪雷达的调试和训练。

Abstract:

A radar intermediate frequency simulator is designed and the component parts and operational principle were introduced in this paper. The radar intermediate frequency simulator can generates the sum signal, elevation difference signal, and azimuth difference signal of monopuls radar. It can operate online or by itself. And it can produce different modulation modes of radar intermediate frequency echo, such as general pulse, LFM pulse and so on. It can be applied to debugging and training of many kinds of new style tracking radar, such as modern phased array radar.
