Microwave Attenuation in Rain; a Dual Wavelength Radar Study
Microwave attenuation in rain at C-band. observed in radar data from Alberta. Canada, has been assessed by means of two different estimators: one employing KDP measured simultaneously by an S-band radar and the other a comparison of synchronised Sand C-band reflectivity measurements. While good agreement between the two has been found in some cases, in others the second method gave a larger est...
متن کاملRain rate and rain attenuation prediction for satellite communication in Ku and Ka bands over Nigeria
Rain rate and rain attenuation predictions are one of the vital steps to be considered when analyzing a microwave satellite communication links at the Ku and Ka bands. In this paper, tools for the prediction of rain rate and rain attenuation are presented in the form of contour maps for Nigeria using a massive rainfall data bank of 30 years which are taken from measurements made from the coast ...
متن کاملSimulation of Space-borne Radar Observations of Precipitation at Ku and Ka Band
Global Precipitation Measurement (GPM) is poised to be the next generation precipitation observations from space after the TRMM mission. The GPM will carry a dual-frequency precipitation radar (DPR), operating at Ku and Ka band frequencies. Since space-borne precipitation observations have never been done in Ka band before, extensive research work on dualfrequency radar, including electromagnet...

متن کاملCharacterization of atmospheric precipitation effects on spaceborne synthetic aperture radar response at X, Ku, Ka band
Space-borne X-band synthetic aperture radars (SARs) provide a unique opportunity to measure rainfall over land with unsurpassed spatial resolution of about few hundred meters. This work explores the potential of space-borne X-SARs to estimate rainfall over land from both a model and retrieval point of view. The main objective is to provide a framework for a physically-based inversion of SARs me...
