摘要
通过对CTL-713C数字化天气雷达回波标定原理和方法的阐述,从雷达参数的测量、A/D变换及视频积分处理、测试仪器的稳定性及精确度等几方面因素对造成雷达回波强度标定误差进行了分析,分别得出几种情况下可能出现的误差值,对测试环境与人为可能造成的回波强度标定误差进行了说明。给出雷达回波强度标定结果准确性的检验方法,并对雷达回波强度标定工作中的关键问题进行了总结。
The calibration errors are analyzed in the aspects of radar parameter measurement,A/D transformation,video integration processing,precision and stability of measuring instruments,etc,through demonstrating the principles and method of CTL-713C digital weather radar echo intensity calibration,and the possible error corresponding to each case is given,respectively.The possible calibration errors in echo intensity resulted from the measuring environment and manual operations are discussed,and the method for exa...
