| Abstract: | With Shuttle Radar Topography Mission(SRTM) 3-second high resolution terrain data,the terrain blockage and coverage of ChInese Next generation RADars(CINRADs) are computed,and the theoretical results correspond with real radar echoes fairly well.In order to quantitatively assess the detecting ability of CINRADs,the authors proposed and illustrated three factors,that is coverage ratio,height-area index,and its equivalent radius.Finally,an overall assessment was given on the 158 CINRADs coverage over China,th... |
