摘要
频率捷变技术作为雷达领域的热门研究方向之一,逐渐受到了国内外学者的重视并在电子对抗领域得到广泛应用。相比于传统固定载频雷达,脉间捷变频雷达可以自主规避干扰覆盖频段,难以被侦察机截获识别,具有独特的主动波形对抗优势。该文系统地介绍了频率捷变雷达的特点,全面梳理了国内外关于频率捷变新体制雷达的研究成果,总结了脉间频率捷变雷达信号处理、雷达接收机系统实现的研究进展,并分析了频率捷变雷达未来的几个发展趋势和所面临的问题。
As one of the hot research directions in the field of radar,frequency agility technology has gradually received the attention of scholars at home and abroad and has been widely used in the field of electronic countermeasures.Compared with the traditional fixed carrier frequency radar,the pulse-to-pulse frequency agility radar can autonomously evade the frequency band covered by interference and are difficult to be intercepted and identified by reconnaissance aircraft,and have unique advantages in active waveform countermeasures.This article systematically introduces the characteristics of frequency agile radar,comprehensively combs the domestic and foreign research results of the new frequency agile radar system,summarizes the research progress of inter-pulse frequency agile radar signal processing and the realization of radar receiver system,and analyzes the future development trends and problems of frequency agility radar.
