摘要
从雷达探测理论出发,结合工作实践,从理论上计算了对流层风廓线雷达的探测高度范围、时空分辨率和测量误差,对数据获取率等方面的测量性能进行了分析。结果表明:通过对风廓线雷达的工作波形和工作模式进行恰当设计,对流层风廓线雷达的测量性能可以达到:最大探测高度12 km以上,最小探测高度150 m,高度分辨率75 m,时间分辨率10 min,风速准确率1 m/s,风向准确率10°,数据获取率不小于80%。分析结论可供风廓线雷达区域布网工作参考。
Depend on the working principles of wind profiling radar and application practice,the sounding altitude,spatial and temporal resolution,and measurement errors of the tropospheric wind profiling radar are calculated,and the data availability is analyzed.The results show： through selecting suitable operating waveforms and modes,the radar detection altitude can range from 150 to 12000 meters,and height resolution can be up to 75 m,temporal resolution to 10 minute,wind speed accuracy to 1 m/s,wind direction to 10°,and data availability to over 80%.The conclusions can be used as references for the regional networking of wind profiling radar.
