The study and real-time implementation of attenuation correction for X-band dual-polarization weather radars
Attenuation of electromagnetic radiation due to rain or other wet hydrometeors along the propagation path has been studied extensively in the radar meteorology community. Recently, use of short range dual-polarization X-band radar systems has gained momentum due to lower system cost compared with …

Multiobjective Optimization and Analysis of Slotted Waveguide Antenna Stiffened Structures
… systems in modern aircraft. Looking at the weather radars used by current aircraft and using the loading estimates of the X-47B from Northrop Grumman, the designs went through several stages in the optimization procedure. The first stage centered around accounting for the stress …

Flexible spatial interpolation and uncertainty quantification : with applications in radar rainfall estimation.
… due to the errors in the available data sources. Weather radars are used to predict precipitation with high spatial and temporal resolution, but do not measure ground level rainfall intensity, which is the quantity of interest. To account for the error resulting from the use of a proxy variable, …

Feasibility of Spectrum Sharing Between Airborne Weather Radar and Wireless Local Area Networks
… feasibility of spectrum sharing between airborne weather radar and wireless local area networks at 9.3 GHz – 9.5 GHz. Characteristics of flight paths of aircraft using airborne weather radar and the low duty cycle of radar transmissions offer unique opportunities for spectrum sharing. But it was …

The development and validation of an X-band dual polarization Doppler weather radar test node for a tropical network
… of three X-band dual polarization Doppler weather radars is in process of being deployed and operational on the western coast of Puerto Rico. Colorado State University and the University of Puerto Rico at Mayaguez have collaborated to install the first polarimetric weather radar network in …

Printed log-periodic feeds for radar applications
… principles of radar are suitable also to the weather radars, used to detect the precipitations at long distance, where the "object of interest” (the target) are the particles of rain and clouds. The detection of these objects involves radar operating at multiple frequencies located in S and C …

Nuevas técnicas para la mitigación de clutter de aerogeneradores en radares meteorológicos
… systems. In particular, this is an issue for weather radar networks. Weather radars see wind turbines as clutter, since they have a strong influence on meteorological outputs such as the estimation of rain intensity or wind velocity. Over the last few years several studies about the impact of …
