P5.2 Moving Clutter Spectral Filter for Terminal Doppler Weather Radar

Adaptation of Rejection Algorithms for a Radar Clutter

In this paper, the algorithms for adaptive rejection of a radar clutter are synthesized for the case of a priori unknown spectral-correlation characteristics at wobbulation of a repetition period of the radar signal. The synthesis of algorithms for the non-recursive adaptive rejection filter (ARF) of a given order is reduced to determination of the vector of weighting coefficients, which realiz...

Detecting weather radar clutter using satellite-based nowcasting products

This contribution presents some initial results from investigations into detection of weather radar clutter by data fusion with satellite-based nowcasting products. Weather radar data from three C-band Doppler weather radars of the Danish Meteorological Institute has been extracted for cases of sea and land clutter caused by anomalous propagation as well as cases of clutter free data. In additi...

Refractivity Measurements from Ground Clutter Using the National Weather Radar Testbed Phased Array Radar

In warm seasons, convective precipitation initiation heavily depends on moisture near the surface [e.g., Dabberdt and Schlatter, 1996; Koch et al., 1997]. A necessary condition for an accurate prediction of convective rainfall is a good forecast of where and when convection will develop. Both prediction and understanding of convection is limited by the lack of high spatial and temporal resoluti...

Data Driven Adaptive Identification and Suppression of Ground Clutter for Weather Radar

An innovative approach for the suppression of ground clutter (GC) contributions from weather radar data is presented. Most of the existing adaptive spectral GC filters (GCF) need a prior knowledge of clutter position, strength and its spectral characteristics. This knowledge is irrelevant for the presented approach because the identification and suppression are entirely data driven. The new app...
