Overview on Airborne Early Warning Radar Technology and Signal Processing Methods

摘要

摘要: 机载预警雷达及其信号处理技术经历了巨大的发展，但也面临着隐身目标、非均匀杂波、复杂电磁环境、目标的识别和多种作战任务的严峻挑战。该文回顾了机载预警雷达及其信号处理技术的发展历程，分析了机载预警雷达面临的反隐身、反干扰、反杂波和目标识别方面的挑战，在此基础上提出了机载预警雷达体制正向数字化、宽带化、协同化、智能化和多功能一体化演变的趋势，最后分析了3D-STAP, MIMO-STAP、宽带检测、认知抗干扰等关键技术，有望对下一代机载预警雷达的研制发挥一定的指导意义。

Abstract: Airborne early warning radar and its signal processing technology have experienced great development, but it is also facing great challenges on stealth target, heterogeneous clutter, complex electromagnetic environment, target classification and a variety of combat missions. In this paper, the development of airborne early warning radar and its signal processing technology is reviewed and the challenges airborne early warning radar facing such as anti-stealth, anti-jamming, anti-clutter and target recognition are analyzed. The development trends of the airborne early warning radar system towards digital, broadband, collaborative and intelligent direction are put forward on this basis. Finally, the key technologies of the signal processing such as 3D-STAP, MIMO-STAP, wideband detection, cognitive anti-jamming are analyzed, which have certain directive significance for the development of the next generation airborne early warning radar.
