摘要

Abstract: There exists a need for a low-cost aircraft collision-avoidance system suitable, and affordable, for general aviation use. The fact that most of all of mid-air collisions occur under high visibility conditions, and many in and near terminal airspace, allows the consideration of optical means such as a LIDAR system for ranging and tracking to other aircraft to determine if a collision threat exists. This paper presents a system parametric analysis and discusses the LIDAR design tradeoffs with consideration of atmospheric attention, false target discrimination, threat scenario, scanning dynamics, wide FOV retroreflector array performance, and sizing for airframe ease of mounting and minimal aerodynamic effects. Further, concepts for the optical design and mechanization of the scanner are presented as well as a pilot warning/display means for evasive maneuver consideration. !7
