Overview on Airborne Early Warning Radar Technology and Signal Processing Methods

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.
