Autonomous infrared doppler radar: Airport surveillance applications

Abstract Infrared Doppler radar (Doppler lidar) sensors provide a unique capability to generate high resolution, three-dimensional distributions of wind and aerosol data. Appropriately processed, these data can be used in the airport terminal area to map hazardous wind shear and turbulence levels, detect and track wake vortices, and monitor slant path visibility. The benefit of the infrared radar relative to its microwave counterparts is the ability to sense clear air hazards, especially those in and around local terrain features. The fact that the infrared radar beam is quite narrow significantly reduces, if not eliminates, artifacts associated with sidelobe-induced ground clutter. Continued rapid developments in the arena of solid-state infrared Doppler radar have yielded substantial advancements in terms of autonomous, stand-alone operation. Such developments have made possible the ability to deploy compact and robust systems that are unattended. This paper summarizes our autonomous pulsed lidar developments and reviews sample results.
