摘要
地物杂波的回波强度相对稳定 ,对成都和新疆地区的地物杂波强度的统计表明 ,地物杂波的雷达反射因子方差分别小于 3db和 1.5db ,因此 ,地物回波可作为一个标准目标 ,用来对天气雷达进行强度的标定。本文给出了这种强度标定的流程图、标定方法和标定结果。使用这种标定方法将大大改善天气雷达的维护和使用质量。
The ground clutter reflectivity factor Z is relatively stable. The standard deviation for the ground clutter reflectivity factor Z is less than 3db and 1.5db in Chengdu and Xinjiang respectively. The flowchart of calibration procedure and calibration result of reflectivity factor Z is given. This calibration method using the ground clutter as a standard will improve radar maintenance and application quality.
