P10.11 Automatic Detection and Removal of Ground Clutter Contamination on Weather Radars
Radar backscatter from the ground can contaminate weather signals, often resulting in severely biased meteorological estimates. If not removed, these clutter returns tend to bias reflectivity high as well as Doppler velocity and spectrum width toward zero. A ground clutter filter (GCF) can mitigate this contamination and provide unbiased meteorological estimates but typically with reduced quali...
متن کاملOn differentiating ground clutter and insect echoes from Doppler weather radars using archived data
Normally wind measurements from Doppler radars rely on the presence of rain. During fine weather, insects become a potential radar target for wind measurement. However, it is difficult to separate ground clutter and insect echoes when spectral or polarimetric methods are not available. Archived reflectivity and velocity data from repeated 5 scans provide alternative methods. The probability of ...
متن کاملGround Clutter Cancellation in Incoherent Radars: Solutions for Eiscat Svalbard Radar
Incoherent scatter radars measure ionosphere parameters using modi®ed Thomson scatter from free electrons in the target (see e.g. Hagfors, 1997). The integrated cross section of the ionospheric scatterers is extremely small and the measurements can easily be disturbed by signals returned by unwanted targets. Ground clutter signals, entering via the antenna side lobes, can render measurements at...
