Jorge L. Salazar, a doctoral graduate from the Electrical and Computer Engineering Department at the University of Massachusetts Amherst, was awarded a prestigious National Center for Atmospheric Research (NCAR) Advanced Study Program Postdoctoral Fellowship. The postdoctoral program provides an opportunity for recent Ph.D. scientists and engineers to continue to pursue their research interests in atmospheric and related sciences. Salazar is currently working at the Earth Observing Laboratory at NCAR in Boulder, Colorado, developing an emerging technology for two-dimensional, electronically scanned, and dual-pol phased array radars for use in atmospheric research.
This development is a critical tool for studying weather and related hazards, especially for retrieving dynamic and microphysical characteristics of clouds and precipitation over rugged terrain or the open ocean, where other radar systems can have major limitations.
Salazar received his Ph.D. from UMass Amherst in July 2012. His doctoral dissertation was entitled "Feasibility of Low-Cost Dual-Polarized, Phase-tilt Antenna Arrays for Dense Radar Networks," and his dissertation advisor was Professor David McLaughlin, Director of the Engineering Research Center for Collaborative Adaptive Sensing of the Atmosphere (CASA).
Salazar's dissertation addresses the feasibility of low-cost, dual-polarized, X-band phased array antennas for use in dense radar networks for weather surveillance. His prototype design was successfully transferred to the CASA industrial and academic partnership. CASA has licensed the design to ITT, EWR, Vaisala, and Raytheon. The Microwave Remote Sensing Laboratory is currently adapting the design for a space-antenna, wind-retrieval, weather radar system. (December 2013)
