摘　　要：风廓线雷达已经广泛应用于国民经济的许多领域,现在对于其应用已不仅仅局限于风场资料,对回波强度、信噪比、速度谱宽等信息的使用也越来越多。因此,对其开展标校工作就显得非常重要。以CFL-03型风廓线雷达为例,介绍了一种风廓线雷达的自动标校技术,从技术方案设计到信号流程、系统硬件组成,以及对其实现方法进行了研究,并用机外仪器对设备进行了测试,将测试结果和自动标校结果进行了对比,对比结果证明该自动标校系统的精度达到了设计目的,能够满足雷达业务运行要求。The wind profile radar has been widely used in many fields of the national economy. The application is not just confined to wind field data, and such information as echo intensity, signal noise ratio, and spectral width of speeds is more and more applied. It is very important to carry out the calibration of the wind profile radar. Taking CFL-03 wind profile radar as an example, a wind profile radar automatic calibration technology is introduced from technology design to signal process. The system composition and realization are discussed, and the radar is tested with outside measuring instrument. The machine test and built-in automatic calibration results are compared. It is concluded that the precision of the automatic calibration system meets the requirements of radar operation and the design goal has been achieved.
