Determination of windspeed within a weather storm using airborne Doppler radar

A real-time airborne pulse Doppler radar signal simulator is developed to detect low-altitude windshear. Using the numerical simulation model of an isolated microburst the radar returns from the undesired objects are obtained using appropriate probabilistic models. The mean radial windspeed is then estimated from the radar returns on the basis of covariance and spectral domain approaches. Numerical simulation results are presented to study the effect of system white noise and the ground moving clutter on the estimation of mean radial wind speed
