Millimeter wave radar network for precipitation mapping
Abstract: The millimeter wave radars have been used in various domains and extensive research is currently in progress for improving this technology. In this research, a novel concept of using millimeter wave radars to obtain surface precipitation is proposed. Algorithms to obtain the rainfall rate at the millimeter wave band using radar parameters such as reflectivity and attenuation is discussed with the help of signal modeling. A new algorithm which corrects for radar signal attenuation in rain as well as ice hydrometeors is also introduced. The attenuation correction obtained using X-band and Ku-band radar data are discussed. A tool which generates the radar signals at millimeter wave frequency band is developed. The various parameters which are used in the signal simulation are explained in detail and the simulation results are presented. The current system architectures used in precipitation mapping are discussed. Using the Dallas-Fort-Worth urban region, simulations are carried out and the potential for using millimeter wave radars to create precipitation maps is presented. Finally, a proposed system of precipitation mapping using millimeter wave radars is also presented.
