Sense and avoid technology developments at Queensland University of Technology.

In recent years, the avoidance strategies have become progressively more complex, yet better aligned to pilot see and avoid behaviour. Significant advances have also allowed the system to be characterised by two mutual exclusive thresholds, one for making avoidance decisions and the other for determining when to stop avoidance behaviour. The importance of this is that existing performance evaluation techniques, used to asses systems, such as TCAS, can be leveraged to simultaneously optimise system parameters, determine performance limits, and visualise design trade-offs. The evaluation framework also follows on naturally from the techniques utilising receiver operating curves used to asses the detection performance using similar techniques. [ABSTRACT FROM PUBLISHER]
