Wavelet based methods for improved wind profiler signal processing

Wavelet based methods for improved wind profiler signal processing

In this paper, we apply wavelet thresholding for removing automatically ground and intermittent clutter (airplane echoes) from wind profiler radar data. Using the concept of discrete multi-resolution analysis and non-parametric estimation theory, we develop wavelet domain thresholding rules,...
