Prof. David Schvartzman of University of Oklahoma

Because of the confluence of previous development projects, technological readiness and reasonable cost, scientific need, and opportunity created by the eventual replacement of parabolicreflector-based radars, now is the time to strongly consider Phased Array Radars (PARs) for atmospheric remote sensing. Unique and flexible capabilities offered by PAR technology have the potential to improve the weather radar products, making PAR technology an attractive candidate for the next generation of weather radars. Although PAR technology was initially conceived in the early 1900's, tremendous advancement of the technology was motivated by the need for advanced air defense capabilities during the World War II. Over the past few decades, this technology has greatly matured in the context of air surveillance and defense applications, making PAR technology more accessible to other applications. Key PAR capabilities that support the needs of advanced 
weather surveillance include: the ability to almost instantly steer the radar beam to an arbitrary direction within the scan sector (i.e., beam agility), the flexibility to dynamically redefine the sampling parameters for each beam position in the scan, and the ability to digitally form multiple simultaneous beams in different directions. Nevertheless, considering that dual-polarization capabilities are a non-negotiable requirement for a future network of weather surveillance radars and the challenges associated with combining these technologies, the feasibility of producing highaccuracy dual-polarization PAR observations has to be investigated. This important question has recently gained attention in the research community, and scientists have begun investigating the implementation and calibration of dual polarization technology on PARs. This talk will focus on the current developments in phased array radar technology, polarimetric radar calibration methods, and the use of phased array radar technology for atmospheric science applications
