Integrity Analysis for Aviation and Automotive Applications.
technology advances, automated systems are being considered for many safety applications
within the aviation and automotive industries. Such applications include airport surface
traffic management systems and automotive lane-keeping systems. Possibly misleading
sensor data must be considered when designing these systems since they operate in the
absence of a human controller. ... read moreCurrently, no integrity requirements (e.g. no sensor
anomaly detection requirements) have been defined for these types of automated airport
surface and automotive applications. This thesis both demonstrates an integrity risk
assessment for an airport surface application and proposes an integrity monitor for an
automated lane-keeping system. Within this work, airport surveillance sensors, such as
radar, multilateration, and ADS-B, are evaluated and modeled, with a specific emphasis
on the impact of their random noise and off-nominal performance characteristics on the
system's integrity. Similarly, for automated lane-keeping, two image processing
techniques - gradient detection and optical flow - are applied to perform a cross-check
in order to verify measurement quality.
