A new hybrid data compression algorithm for weather radar
Ke Ma, Chongyang Li, Haozheng Li · 2016
The existent problem of the weather radar data lies in its too large data which is not conducive to its storage and transmission. This paper put forward a hybrid compression algorithm of the weather radar data that consists of three steps including pre-compression, lossy compression and lossless compression. Firstly, the paper introduced the radar data's types and characteristics, analyzing the pre-compression algorithm; Secondly, according to the practical requirements of the diverse users, it proposed the adoption of lossless compression and lossy compression algorithm for the data; Finally, the flow chart of mixed compression algorithm was presented and verified based on the actual data.
