Abstract :
A lower atmosphere wind profiler, which is a pulse Doppler radar is a useful operation tool which can provide unattended and continuous observation of wind profiles. Since the observed signals are usually degraded by ground clutters which are overlapped with the wind signal it is necessary to develop a method to estimate the wind signal from the observed signals. We propose to use a genetic algorithm to resolve the overlapped signals
