Abstract
Method and apparatus for detecting low altitude wind shear through the use of autocorrelation on the received and processed echo signals. Self Autocorrelation of echo signals and autocorrelation of echo signals from consecutive pulses are used to calculate the low altitude Doppler velocities over distance. In an alternate embodiment, autocorrelation of echo signals from alternate pulses is also required. Wind shear is calculated from low altitude Doppler velocity as a function of location.
