对雷达敌我识别系统中若干问题的研究

Study on Problems in Radar IFF System

二次雷达敌我识别系统用于识别一次雷达检测到的目标的敌我属性，它主要是由询问机和应答机两部分组成。

The secondary radar IFF ( Identification of Friend-or-Foe ) systems mainly consisting of interrogators and transponders , are used to identify the friend-or-foe attribute of the targets that are detected by the primary radar .

在现有的二次雷达敌我识别系统中由于采用全呼叫方式和同频工作，系统内部存在着各种干扰，如窜扰、混扰、占据，这些干扰将对系统的正确识别概率存在着严重的影响。

Due to using the same work frequency and all-direct responding in the systems , there are a great deal of effects such as fruit garbling and capture , which will badly impose the right identification probability of the interrogators .

本文所研制的两个毫米波微带天线阵可应用于毫米波雷达，通信与敌我识别系统等方面。

This dissertation develops two millimeter waves microstrip antenna arrays which can be applied to the millimeter wave radar , the communication and the identification for friend-or-foe .

本论文根据二次雷达系统的现状，设计了一个基于STAGE的二次雷达敌我识别系统的仿真系统，根据仿真结果分析，找出能够降低系统干扰对系统正确识别概率的影响的方法。

According to the actuality of secondary radar system , this thesis devise a simulation for the secondary radar IFF , based on STAGE . Via the analysis of several results of simulations , find out some means to improve the identification probability .
