Allistair Moses to present at SPIE Defense, Security and Sensing on April 28, 2011

Ph.D. student Allistair Moses will present a paper, entitled "UAV-borne X-band Radar for MAV Collision Avoidance" co-authored by Allistair, myself, Dr. Michail Kontitsis and Dr. Kimon Valavanis, at the SPIE Defense, Security and Sensing conference in Orlando, FL on April 28, 2011.

Abstract (Slides attached):

Increased use of Miniature (Unmanned) Aerial Vehicles (MAVs) is
coincidentally accompanied by a notable lack of sensors suitable for
enabling further increases in levels of autonomy and consequently,
integration into the National Airspace System (NAS). The majority of
available sensors suitable for MAV integration are based on infrared
detectors, focal plane arrays, optical and ultrasonic rangefinders,
etc. These sensors are generally not able to detect or identify other
MAV-sized targets and, when detection is possible, considerable
computational power is typically required for successful
identification. Furthermore, performance of visual-range optical
sensor systems can suffer greatly when operating in the conditions
that are typically encountered during search and rescue, surveillance,
combat, and most common MAV applications. However, the addition of a
miniature radar system can, in consort with other sensors, provide
comprehensive target detection and identification capabilities for
MAVs. This trend is observed in manned aviation where radar systems
are the primary detection and identification sensor system. Within
this document a miniature, lightweight X-Band radar system for use on
a miniature (710mm rotor diameter) rotorcraft is described. We
present analyses of the performance of the system in a realistic
scenario with two MAVs. Additionally, an analysis of MAV navigation
and collision avoidance behaviors is performed to determine the effect
of integrating radar systems into MAV-class vehicles.
