Abstract

Data compression technology is one of the essential core technologies for remote measurement and control of future intelligent ships. The quality and volume of the compressed digital video of shipborne radar should meet the requirements of intelligent ships. The digital video compression technology of shipborne radar and the bandwidth of marine communication network are the main factors that affect radar digital video compression quality. In this paper, according to the content of the radar echo area, four ranges of shipborne radar digital video are selected, and the high-efficiency digital video coding standards H.264/AVC, H.265/HEVC, HEVC-SCC, VP9 and AVS2 are used for radars of different ranges. Digital video uses the same encoding configuration to conduct simulation experiments and compare compression performance. The simulation results show that the digital video quality of the shipborne radar compressed by these video coding standards will continue to change with the fluctuation of the network bandwidth. When the bitrate is low, the compression performance of the encoder is improved faster, while the compression performance of these video coding standards gradually approaches at a higher bitrate. The performance of the codec also depends on the complexity of the radar digital video content. The larger the range, the lower the content complexity and the better the performance.
