1090ES关键信息解码算法优化及实现Optimization and implementation of key message decoding algorithm for 1090ES
张鹏,何光亮
摘要(Abstract)：
以1090ES广播式自动相关监视(ADS-B)系统的飞机位置报文为信号源,采用ARM Cortex-M4内核的微控制器为硬件平台。针对目前空中交通管制对数据处理的实时性和准确性的要求,对空中目标飞机的经纬度和高度等关键信息进行解码。分析以往查表法在解码中的优缺点,归纳总结和实现了公式法在ADS-B系统位置报文中高度信息的解码。通过在真实数据环境下实验验证,其实验结果表明该方法能很好地克服常规算法繁琐、占用内存资源多等缺点,且软硬件实现更加方便、快捷。
