摘要: 多样的基数据文件格式一直是困扰新一代天气雷达资料应用的一个问题。为了解决这一问题,本文分析我国新一代天气雷达的各种不同的基数据文件格式,提出一种自动识别的方法。通过对文件二进制信息的自动分析,区分是否是基数据文件,识别基数据文件的类型。本文方法流程简单、识别准确、扩展容易,可应用于雷达数据读取模块之前,使软件以较小代价兼容多种雷达基数据文件。

Abstract: The diversity of raw data file formats is a problem for application of CINRAD (China New Generation Radar) data. In order to solve this problem, different data file formats of CINRAD are analyzed, an auto-identification method is proposed. Raw data file formats are identified by auto-analysis of binary information. The proposed method is of simple flow, high accuracy rate and high expandability, it can be applied before module reading by radar data, and thus makes software compatible with various radar data formats at low expense.
