Feasibility of a Passive Collision Avoidance System (PCAS) Based on Staring Infrared Sensors

Abstract

This report finds that a light weight, passive collision avoidance (PCAS) system based on uncooled LWIR sensors is feasible for Hunter/Predator class UAVs. The candidate PCAS system is analyzed using a statistical measure based on warning time provided. Typically warning times of 10s of seconds could be provided with very low probability of missed detection due to encounters with light aircraft under contrast reversal conditions.
