多权重排序算法在雷达回波团识别中的应用
首发时间:2021-01-04
摘要:新一代天气雷达组合反射率的回波图像经过离散回波剔除和边界化处理以后,可以获得回波团图像。应用多权重排序算法,通过对不同时间段回波团图像的重合率分析,就可以识别出不同时间段雷达回波中的同一回波团。综合该回波团在不同时刻的移动速度、移动方向、强度变化等信息,再通过路径预测算法,就可以实现新一代天气雷达回波移动路径的预测。

Application of multi weight sorting algorithm in radar echo group recognition
Abstract:After discrete echo elimination and boundary processing, echo group images can be obtained from the echo images with combined reflectivity of the next generation weather radar. By using the multi-weight sorting algorithm and analyzing the coincidence rate of echo group images in different time periods, the same echo group in radar echoes in different time periods can be identified. By integrating the information of moving speed, moving direction and intensity change of the echo cluster at different times, the path prediction algorithm can be used to predict the echo moving path of the new generation weather radar.
