基于DeltaOS的测量定位雷达对动目标处理和显示研究

摘要

针对测量定位雷达的高实时性和国家武器装备的安全性问题,研究实现了基于龙芯3A处理器在实时操作系统(DeltaOS)下对海上动目标舰船的精度测量.通过研究DeltaOS系统下的图形开发和实时任务调度机制,详细阐述了Del-taOS操作系统下的GUI设计架构,采用滤波和外推算法对动目标舰船运动轨迹进行估计和显示.现场实测实验表明该国产系统建构可以满足对海上运动舰船的实时精确测量定位的要求.%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.
