In the interest of aviation safety, NASA and the Federal Aviation Administration (FAA) are jointly conducting research to determine the applicability of airborne, coherent Doppler radar techniques to detect early microburst in wind shear conditions during aircraft takeoff and landing. If early detection of these severe wind shear conditions can be demonstrated, avoidance maneuvers can be excercised and significantly reduce the probability of aircrft disaster. Researchers have developed a computer model of the radar which predicts its response when viewing a simulated microburst against the simulated clutter background of an airport, the so-called radar-microburst-ground clutter model. Studies employing this model revealed that Doppler radar can accurately detect microburst ahead of the aircraft in time for pilot evasive response, but flight experiments will be required for complete performance evaluation of the system.
