So, first of all, the research on the structure of WDAR had been carried out.
本文首先对数字阵雷达试验系统的总体结构进行了较为深入的研究。
The wide-band digital array radar (WDAR), which accomplishes the transform between digital data and analog signal in the radar array, is the trend of the development of the phased array rader.
数字相控阵雷达宽带宽角扫描存在波束指向偏差和孔径渡越问题，导致信噪比降低，脉压主瓣展宽，距离分辨率下降。
