摘要

由于一次雷达在避免民用航空和军用航空的飞行冲突方面发挥着重要作用，一些国内机场安装了一次/二次雷达。一些空中交通管制初级雷达采用脉冲压缩技术。它最大的优点是增大了雷达距离，提高了距离分辨率。介绍了线性调频(LFM)和脉冲压缩的概念，分析了频谱和脉冲压缩原理，总结了脉冲压缩技术的优点，并给出了应用模型。

Application of Pulse Compression Technique in Air Traffic Control Primary Radar

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 biggest 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 advantages of pulse compression technique and gives an application model.
