- 摘要:
- 对724XSP与SCRXD-01型X波段多普勒天气雷达非标格式基数据的数据结构、存储格式进行试验研究,对非标格式基数据的组织逻辑作出说明。通过实验验证了:(1)SCRXD-01型雷达体扫非标格式基数据每径向的各要素数据占用2千字节,前1千字节是有效数据,对应1千个距离库,后1千字节通常为空字节;(2)文件头中一些字段记录的值与实际情况不符;(3)径向间的夹角是不均匀的,有的大于1.5°,某些方位上将出现径向数据不能覆盖的空缺区域。并提出正确解析X波段天气雷达体扫非标格式基数据文件的算法和流程,为数据正确解析、数据转换以适应软件数据兼容、业务应用等提供帮助。
- Abstract:
- This article conducts experimental research on the data structure and storage format of non-standard basis data for the 724XSP and SCRXD-01 X-band Doppler weather radar,and provides a explanation of the organizational logic for non-standard base data.Through experiments,it has been verified that: The SCRXD-01 radar non-standard base data of volume scanning occupies 2 kilobytes for each radial element data,The first 1000 bytes are valid data,corresponding to 1000 distance libraries,and the last 1000 bytes are usually empty bytes; the values recorded in some fields in the file header do not match the actual situation; The included angle between the radials is uneven,some of which are greater than 1.5 °,and there will be gaps in certain directions that cannot be covered by radial data.This article proposes an algorithm and process for correctly parsing non-standard base data files of X-band weather radar,providing assistance for correct data parsing,data conversion to adapt to software data compatibility、business application,etc.
