多普勒天气雷达回波数据质量检测及控制方法

Quality inspection and control method for echo data of Doppler weather radar

本文提出了一种基于天气雷达回波强度和速度数据的质量检测方法。通过采集天气雷达按统一的参数进行标定后的晴空标准地物回波强度作为模版,与实时采集的回波强度进行比较和误差分析,以及通过移相来自动检测速度数据理论值和实测值的误差大小,对回波强度数据和速度数据质量进行检测和校正,以此来实现对天气雷达回波数据的质量控制。

This paper proposes a quality inspection method based on echo intensity and speed data of Doppler weather radar. The real-time echo intensity data is compared with a stencil that is collected on clear day from calibrated radar with uniform parameter standard. And the comparative errors are analyzed on the measured and theoretical value of the speed data through phaseshift. Based on the above comparisons, the echo intensity and speed data are detected and corrected to achieve quality control for echo data of weather radar
