Test and Integration of a Detect and Avoid System

Abstract

Remotely Operated Aircraft (ROAs) currently do not have convenient access to civil airspace due to their inability to provide an onboard capability to “see and avoid” air traffic. Defense Research Associates, Inc. and AFRL/SNJT have developed affordable technology based on silicon charge couple device sensors and passive moving target detection algorithms. Previously, an all-software implementation of the algorithms demonstrated concept feasibility by using video data recorded during flight testing. This paper documents subsequent implementation and field testing of a real-time version of the system with field programmable gate arrays handling the detection processing and multiple sensors to demonstrate the wide field of regard required. The implementation met demonstration goals by functioning reliably in real-time and providing detection and false detection performance comparable to that of the previous, non-real-time version.
