| 摘 要： | 为了利用毫米波雷达的回波数据精确地反演得到云的宏微观物理特性，必须对研制的毫米波雷达进行定标.本文重点介绍了国外几种定标方法：单个系统各参数贡献的定标；大雨滴对毫米波雷达的定标；三角反射器以及金属球对毫米波雷达的定标；利用海洋表面后向散射技术的定标以及Cloudsat 作为雷达校准器的定标.这些定标方法对于国内毫米波雷达更好地应用于实际探测具有重要的研究价值.

| Abstract: | To accurately retrieve the macro-and micro-physical parameters of cloud by means of radar echoes,the developed millimeter-wave cloud radar must be calibrated.In this paper,several domestic and abroad calibration methods are introduced,such as the calibration of the contribution of individual system parameters;the calibration of raindrop,triangular corner reflectors and metal sphere;the calibration using the backscattering technology of ocean surface,Cloudsat as radar calibrator.These calibration methods are of great value for the application of domestic millimeter-wave cloud radar in practical remote sensing. |
