Research And Application Of Radar Data Processing And It's Real-time Task Scheduling

At present, with the increasing of air traffic, it has required many new requirement for the air traffic system. It doesn't meet the requirement of civil air transport only by expansive importing foreign ATC products any more. It's crucial to developing out own ATC System with independent intellectual property. Radar Data Processing(RDP) is critical technology in Air Traffic Control(ATC) System. RDP receive observation from sensor and processing radar data to tracking target. RDP provide position, velocity, characters and maneuver of target. Beside Processing Radar Data correctly, it also requests the Radar Data must be processed in stated time and output. otherwise it will course so serious result as that the user can't make the right decision sequentially bring dangerous to flight security. This thesis is based on the work that I've done when I was an internship in WiseSoft Ltd. From July 2004 to March 2006. This thesis mainly discusses the key multi-sensor data fusion technology of Air Traffic Control and By analyzing timing requirement model of Radar Data Processing task, the RMA-schedulability of the task is tested.(1) Single-radar target correlation and tracking filter research: In tracks correlation, it is most important that design a correct correlation gate size and paring algorithm for observation and tracks. The common tracking filter algorithm is discussed: Kalman andα-βtracking filter algorithm. Multi-mode Kalman tracking filter algorithm and multi-modeα-βtracking filter algorithm is also discussed.(2) Multi-radar track fusion algorithm research: A scheme of time and space of multi-radar and ADS is designed, coordination transform, north rectification and...
