| Abstract: |
| To track and inquire airplanes continuously and stably, the data processing modu
le 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 processi
ng in Vxworks RTOS when the airplane changes course or turn. Outfield test demon
strates that the realtime monitoring of airplanes can be achieved through ration
ally dividing the data processing module of ATC SSR and implementing IMM filteri
ng technique,and at the same time normal communication with airplane can be kep
t properly. |
