Radar (United States)
2016
After decades of research and development, the WSR-88D (NEXRAD) network in United States was upgraded with dual-polarization capability, providing polarimetric radar data (PRD) that have potential to improve weather observations, quantification, forecasting, warnings. The networks China other countries are also being capability. Now, polarimetry technology having matured, PRD available both nationally globally, it is important understand current status future challenges opportunities. impact...
A radar simulator capable of generating time series data for a polarimetric phased array weather has been designed and implemented. The received signals are composed from high-resolution numerical prediction model. Thousands scattering centers (SCs), each with an independent randomly generated Doppler spectrum, populate the field view radar. moments SC spectra derived model, positions updated based on 3-D wind field. In order to accurately emulate effects system-induced cross-polar...
