ASR-9 Microburst Detection Algorithm
The ASR-9 Wind Shear Processor (WSP) is intended as an economical alternative for those airports that have not been slated to receive a Terminal Doppler Weather Radar (TDWR), but have, or will be receiving, an ASR-9 radar. Lincoln Laboratory has developed a prototype ASR-9 WSP system which has been demonstrated during the summer months of the past 3 years in Orlando, Florida. During the operati...
متن کاملAn agent network for microburst detection
Meteorological data provides a rich source of imagery which is well suited to the growing eld of agent networks based image processing. Here we discuss one such system which analyses Doppler and reeec-tivity radar volumes to detect microbursts (windshear events). The system employs a network of agents, each performing a subtask of the detection, with message passing between agents. The various ...
متن کاملNumerical Simulations of Gust Front / Microburst Collision Dynamics
A microburst is a local, intense downdraft which induces an outburst of damaging winds near the ground which extends 4 km or less. Microbursts are of interest to researchers because of the strong, occasionally damaging surface winds they produce, and the hazardous wind patterns they create for aircraft in the landing or takeoff phases of flight. The dynamics and aircraft hazards posed by an iso...
متن کاملA Study of Dry Microburst Detection with Airport Surveillance Radars
This report evaluates the capability of Airport Surveillance Radars (ASRs) for the detection of low altitude wind shear associated with the outflows of dry microbursts. It describes results of simulations of dry microburst observations by an ASR. These simulations incorporated weather and clutter data collected by the FL-2 pencil-beam Doppler weather radar at Denver Stapleton Airport in 1988 an...
متن کاملModified Guidance Laws for Escaping a Microburst with Turbulence
This paper introduces Modified Altitudeand DiveGuidance laws for escaping a microburst with turbulence. First, a new safety metric is constructed that quantifies the aircraft upward force capability in a microburst encounter. In the absence of turbulence, the safety factor is shown to be a decreasing function of altitude. This suggests that descending to a low altitude may improve safety in the...
