摘要
基于一次雷达在防止军民航飞行冲突方面有着特殊的意义和作用,国内很多机场都有一/二次合装雷达。大多数的一次航管雷达都采用了脉冲压缩技术,脉冲压缩技术最显著的特点是在不增加峰值功率的情况下,既保证了雷达作用距离,又提高了距离分辨力。文中对线性调频脉冲压缩的基本概念,频谱和压缩原理进行了分析,总结了脉冲压缩技术的优点,给出了实际应用中的一个模型。
Because primary radar plays an important role in averting flight conflict between civil aviation and military aviation,some internal airports installed primary/secondary radars.Some air traffic control primary radars use pulse compression technique.The big-gest advantage of it is the increasing radar range and improving range resolution.This paper introduces conception of Linear Frequency Modulation （LFM）and pulse compression,analyzes the frequency spectrum and pulse compression principle,summarizes the advanta-ges of pulse compression technique and gives an application model.
