Computer simulation of weather radar signals

Abstract: Computer simulation is largely used in radar signal analysis. This present work treats the simulation of precipitation echoes in weather radar application. where two different approaches are used for simulating weather radar signals. These simulated signals offer great potential for estimating spectral moment and various polarimetric variables .One of the methods uses a time domain approach while the other uses the frequency domain approach. We show that the simulated signals reflect the desired properties. Both the simulation algorithms are based on a macroscopic model, i.e. a random processes with an assigned power spectrum.
