ABSTRACT:
Clutter present in radar return signals as used for wind profiling is substantially removed by carrying out a Daubechies wavelet transformation on a time series of radar return signals. The smoothly varying nature of the return from clutter provides a relatively small number of high amplitude components in the wavelet transformation, which are truncated to remove the clutter. Inverse transformation yields a time series having had a significant amount of clutter removed, without distortion of the radar return from turbulence, which can then be processed to provide useful wind profile data.
