Identity confidence estimation of manoeuvring aircraft

Holtzhausen, Petrus Jacobus (2006-12)

Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2006.


A radar system observes an aircraft once during each scan of the airspace, and uses these observations to construct a track representing a possible route of the aircraft. However when aircraft interact closely there is the possiblility of confusing the identities of the tracks. In this thesis multiple hypothesis techniques are applied to extract an identity confidence from a track, given a set of possible tracks and observations. The system utilises numerous estimation filters internally and these are investigated and compared in detail. The Identity Confidence algorithm is tested using a developed radar simulation system, and evaluated sucessfully against a series of benchmark tests.
