摘要:
径向干扰回波是天气雷达回波中常见的一种异常回波,存在于我国多个雷达站点的回波中。它在径向上呈条辐状分布,经常和降水回波在很多区域是重叠的。对回波数据进行退距离订正值及衰减订正值处理后,再对多组受到干扰的雷达体扫资料进行分析,得出径向干扰回波的一些普遍特征;然后提出径向干扰回波的识别方法,最后通过实例进行效果验证,结果表明该方法能够对径向干扰回波进行有效地识别。
Abstract:
Radial interference echo is one kind of abnormal echo and existsat many radar stations in our country. It radially distributes like stripe and is often overlapped with precipitation echoes in many areas.In this paper, after processing the value of distance retreat correction and attenuation correction, we analyzed the multi body radar volume sweeping data, and obtains some general characteristics of the radial interference echo; thenwe analyzed the radar scanning data of several groupsand obtained some common characteristics of the radial echo. Furthermore, the recognition method of radial interference echo was put forward. Finally, an example was given to verify the effectiveness of the method. The results showed that the method can effectively identify the radial interference echo.
