Development of wideband digital array radar

As the further development of narrowband digital array radar, wideband digital array radar(WDAR) get more and more research all over the world, for it not only has the advantages of narrowband digital array radar such as compact structure, large dynamic range and flexible digital beam control ability, but also can do high resolution processing such as target imaging. In this paper, based on studying some existing experimental platforms of WDAR, the authors present the basic architecture and function modules of WDAR, analyze the characteristics of WDAR compared with conventional radar, and then some key technologies of WDAR are concisely discussed, the last section conclude the paper.
