【摘要】 为了持续稳定跟踪和询问到空中客机,基于航管二次雷达工作原理,设计了航管二次雷达数据处理功能模块。在Vxworks嵌入式操作系统上采用交互多模滤波技术完成了对客机改变航道或转弯时的航迹跟踪和数据处理。外场试验结果表明,通过航管二次雷达数据处理功能模块的合理划分以及采用交互多模滤波跟踪技术能实现对空中客机的实时监视,并与其保持正常通信。更多还原

【Abstract】 To track and inquire airplanes continuously and stably,the data processing module of secondary surveillance radar(SSR) for air traffic control(ATC) is designed based on the operation principle of the radar.The interactive multi-mode(IMM) filtering technique is adopted to realize flight path tracking and data processing in Vxworks RTOS when the airplane changes course or turn.Outfield test demonstrates that the realtime monitoring of airplanes can be achieved through rationally dividing the data processing module of ATC SSR and implementing IMM filtering technique,and at the same time normal communication with airplane can be kept properly.更多还原
