A novel wavelet-based method for intermittent clutter removal from wind profiling radar data

Intermittent clutter produced by flyers such as birds is a severe interference for wind detecting. For resolving the problem of clutter rejection, a method based on wavelet coefficients replacement is suggested. According to the clutter characteristics of the clutter bursting and short duration gained by the echoes analyzing, a novel method for the clutter recognition based on power consistency checking of different spectral integration signals in the wavelet transform domain, clutter discriminant function and clutter suppression method based on counterpart scale wavelet coefficients replacement are proposed. By the data measured from field testing, high efficiency of clutter rejection is verified.
