Performance Comparison of Pulse Pair and 2-Step Prediction Approach to the Doppler Estimation

Abstract

This work concerns the use of terrestrial pulsed Doppler weather radar echo to estimate windshear hazards disastrous for airplane approach and landing. Two different methods are used to estimate the received Doppler spectrum moments. The second central moment which is the variance of the wind velocity is called width or windshear. One method is in the time domain, while the other is in the frequency domain. These simulations which lead to comparison of the results assumes that the signal portions of the spectrum are approached with Gaussian shape
