Reflectivity of radar
Web1. apr 2009 · A major limitation of improved radar-based rainfall estimation is accurate calibration of radar reflectivity. In this paper, the authors fully automate a polarimetric method that uses the consistency between radar reflectivity, differential reflectivity, and the path integral of specific differential phase to calibrate reflectivity. WebFurthermore, the reflectivity for horizontally polarized signals is less than vertically polarized signals for the same sea state over the range of grazing angles considered. Maritime Surveillance Radar Example Calculating Clutter-to-Noise Ratio Consider a horizontally polarized maritime surveillance radar system operating at 6 GHz (C-band).
