Horizontal Collision Avoidance Systems Study.
Abstract
This report presents the results of an analytical study of the merits and mechanization requirements of horizontal collision avoidance systems (CAS). The horizontal and combined horizontal/vertical maneuvers which provide adequate miss distance with minimum initial range, minimum deviation off track, and acceptable turn rates are found. Horizontal maneuvers are compared with vertical maneuvers and speed control for collision avoidance in terms of initial range requirements, deviation off track and flight path time loss. Requirements for implementing an airborne horizontal CAS are outlined. Digital filtering is analyzed for estimating airspeed and relative heading from noisy range and bearing measurements between aircraft. An algorithm (suitable for airborne mechanization) is developed for computing appropriate collision avoidance maneuvers. The effects of dynamic and measurement errors on the CAS's ability to provide safe miss distance are examined.
