Integrity of tracks estimated by detect and avoid tracking system

Abstract

A system comprises a processor onboard a vehicle, surveillance sensors, and a DAA module that receives sensor measurement tracks and includes a tracking system that tracks objects in an environment around the vehicle. The tracking system comprises a data association module that includes a track-to-track function that outputs main solution and sub-solution tracks with track information. An integrity module communicates with the DAA module and comprises a track integrity system in communication with the data association module and operative to provide integrity checks. The track integrity system compares, selects, and outputs a main solution track or sub-solution tracks based on correlated tracks provided by the track-to-track function and solution separation; sends a track solution that passes integrity tests to a prune function, and sends tracks that fail to pass integrity tests to the data association module; and assures the integrity of tracks correlated and estimated by the tracking system.
