Microburst precursor detection utilizing microwave radar

摘要

A microburst precursor detector samples radar returns from meteorological radar signal reflectors and processes the signal returns in a statistical manner to determine average radar reflectivity and to extract Doppler signal parameters. The vertical velocity in still air and the vertical velocity of the meteorological radar reflectors are respectively determined from the average reflectivity and the Doppler signal parameters. The difference between the two vertical velocities is taken to determine the vertical wind velocity. The vertical wind velocity and the average reflectivity are processed to predict the occurrence of a microburst.
