Abstract
This invention discloses a process for generating wind profiler data which is free of fixed ground clutter contamination. The fixed ground clutter contamination is removed based upon the different decorrelation times of noise, clear air signals, and clutter. A nonlinear regression is used estimate the clutter content of the radar return which is then subtracted from the time series. This process is capable of removing broadband clutter from the desired clear air signal even though both may occupy the same Doppler frequency.
