船舶接收雷达信号回波数据压缩算法研究

Research on data compression algorithm for ship receiving radar signal

船载雷达是船舶导航系统的重要组成设备,在船舶近海航行过程中发挥了重要作用。由于船载导航系统的存储空间有限,而雷达信号回波数据对存储空间的要求非常高,为此,如何利用无损数据压缩算法解决船舶雷达系统存在的问题已成为人们研究的重点。本文以字典编码算法为基础提出了LZW数据压缩算法,该算法提高了数据传输效率,有效降低了数据储存占用的空间。

Shipborne radar is an important component of ship navigation system, and plays an important role in the process of ship's offshore navigation. Because the storage space of ship navigation system is limited, and the requirements of radar echo data on the storage space is very high, therefore, how to solve the existing marine radar system using nondestructive problems become the focus of the study of data compression algorithm. This paper proposed a LZW data compression algorithm based on the dictionary coding algorithm, which improves the data transmission efficiency and reduces the space occupied by the data storage effectively.
