| Popis: | In order to probe into the data acquisition method of radar echo navigation information technology, the radar unit constitution, the compression principle of sampling data of Lempel-Ziv-Welch (LZW) algorithm and two common compression algorithms are introduced. The influence of network transmission speed on radar echo data acquisition in VxWorks system is also studied. The flow chart of the compression implementation and the network transmission speed comparison diagram are analyzed. The experimental results show that the LZW compression algorithm can achieve a satisfactory compression rate when the radar echo navigation data acquisition is carried out. At the same time, users can use the memory file in VxWorks to read and write, which can speed up the network transmission. Based on the above finding, it is concluded that the data acquisition and research based on radar echo navigation information technology can speed up the network transmission by using the VxWorks system. |
