Abstract：In view of the high real-time performance of the location radar and the safety of the national weapons,the accuracy measurement of the moving target ship based on the Loongson 3A processor under the real-time operation system(DeltaOS)is real-ized.By studying the graphics development and real-time task scheduling mechanism under the DeltaOS system,the design archi-tecture of GUI under the DeltaOS operating system is elaborated in detail.The method of filtering and extrapolation is used to esti-mate and display the moving track of the moving target ship.The field test shows that the construction of the domestic system can meet the requirements for real-time accurate measurement and positioning of marine ships.
