捷变频PD雷达导引头目标及干扰回波模拟器设计

Design of Simulator of Target and Jamming Echo for Frequency-agile Pulse Doppler Radar Seeker

捷变频雷达导引头目标与干扰回波信号的研究目的是为了满足捷变频雷达导引头在研制开发中各项软硬件功能调试的需求,研制一部通用型的捷变频雷达导引头目标与干扰回波模拟系统;表征机动目标运动模型的主要参数,提出了目标及干扰回波模型的建立方法,并对回波模拟进行分析,采用DRFM和DDS设计出具有实时模拟能力的中频回波信号源,在此基础上对捷变频雷达导引头目标与干扰回波模拟器进行了设计;试验证明,该模拟器达到了设计要求,有较强的工程应用价值。

This topic is to meet the needs of the debugging in hardware and software during the frequency-agile PD radar seeker researching and developing.A current echo of target and jamming simulate system is manufactured in the research.This paper particularizes the prime parameters which represent the echo of moving targets,and provides a method to simulate the echo of target and jamming,and gives the analysis of echo＇s simulation,DRFM and DDS,it can be used design a real-time radar IF echo signal generator,On the basis of the generator,designs the Simulator of target and jamming echo for frequency-agile Pulse Doppler Radar Seeker.Practice show the requirement of design is met,the introduction is useful to engineering application.
