【摘要】 采用航天飞机雷达地形测绘使命(SRTM)高程数据对天气雷达净空环境进行评估,可有效提高雷达选址评估效率。利用人工测量数据和SRTM数据进行天气雷达净空环境评估对比试验,结果表明基于该数据的天气雷达净空环境评估算法总体与人工测量方法具有较好的一致性。采用方位矫正和距离矫正算法后,基于该数据的天气雷达净空环境评估算法精度明显提高。更多还原

【Abstract】 Shuttle Radar Topography Mission(SRTM) data were used to evaluate the clearance environment and the site-selection evaluation efficiency of radar was effectively improved.In this paper,the comparative experiment of weather radar clearance environment assessment is carried out by using manual measurement data and SRTM data.Error analysis of this method suggested that the evaluation algorithm of weather radar clearance environment based on SRTM was matching with the artificial measured data.The calculation error was significantly reduced when corrected with azimuth correction and distance correction algorithms.更多还原
