摘　　要：为了解决雷达装备性能参数测量训练人员多装备少的矛盾以及雷达部队时常需要担负战备值班任务,无法腾出空闲的装备来进行训练,论文采用上位机+单片机+直接数字频率合成(DDS)模块+功率控制模块架构,开发了雷达中频脉冲信号产生平台。该平台上位机通过串口通信对两个单片机控制,一个单片机控制DDS模块来产生模拟雷达中频脉冲信号,中心频率、重频、脉宽、带宽等参数灵活可变;一个单片机控制功率模块,控制输出信号的功率,放大后的信号然后经过功分器,一路用于检波,一路用于输出。平台产生的雷达中频脉冲信号种类多、性能稳定;上位机界面友好、美观、操作简单,非常便于训练使用,具有一定的推广性。In order to solve the contradiction of more personnel and less equipment in the measurement and training of radar equipment performance parameters,as well as the fact that radar units often need to undertake combat readiness duty tasks and cannot free up idle equipment for training.This paper adopts the architecture of upper computer+microcontroller+direct digital frequency synthesis(DDS)module+power control module to develop a radar intermediate frequency pulse signal generation platform.The upper computerof the platform controls two microcontrollers through serial communication.One microcontroller controls the DDS module to generate analog radar intermediate frequency pulse signals,with flexible and variable parameters such as center frequency,repetition rate,pulse width,and bandwidth.Another microcontroller controls the power module and controls the power of the output signal.The amplified signal is then passed through a power divider,one for detection and the other for output.The platform generates a variety of radar intermediate frequency pulse signals with stable performance.The upper computer interface is friendly,beautiful,and easy to operate,making it very easy to train and use,and has certain promotional value.
