为解决气象雷达数据量过大,不利于存储和传输的问题,提出了一种综合气象雷达数据压缩方法,由多种数据压缩算法构成。首先,分析了气象雷达的数据种类与特点,介绍了一种预压缩算法;然后,依据用户实际需求,提出了无损数据压缩和有损数据压缩两类压缩算法,并对每一类压缩算法进行详细描述,最后用实际数据验证本文提出的压缩算法效果。
In order to solve the problem that the data of meteorological radar is too large and not conducive to storage and transmission, an integrated weather radar data compression method is proposed, which consists of a variety of data compression algorithms. Firstly, the types and characteristics of meteorological radar data are analyzed and a pre-compression algorithm is introduced. Then, two types of compression algorithms, lossless data compression and lossy data compression, are proposed according to the actual needs of users. Detailed description, finally with the actual data to verify the effectiveness of the proposed compression algorithm.
