Dr. McDaniel Selected to Receive the Prestigious National Science Foundation (NSF) CAREER Award
The NSF has awarded Dr. McDaniel with a $625k research grant titled "CAREER: UAV-Based Radar Suite for Bulk-Snow Characterization and Risk Management." This CAREER project will encompass both the development of a new UAV-based custom snow-penetrating sensor technology and enable research on snow hydrology and snow-loading on freshwater lakes and river ice. The technological research will produce fine spatiotemporal data using intelligent monitoring capabilities that allow mapping of snow loading and ice thickness on freshwater lakes and rivers through 3D echogram formation and wind redistribution of snow using coherent change detection. These data would support actionable risk management strategies that drastically improve residents’ lives and socioeconomic resiliency. The CAREER project will also incorporate aspects of this research in graduate and undergraduate courses, includes experiential laboratory exercises through design-build projects, and as part of the RISING STudent Ambassador Research (RISING STAR) program will involve Native American and first-generation students to increase diversity and interest in STEM careers

IEEE Transactions on Instrumentation and Measurement (TIM) Paper Accepted - Led by Ms. Rachel Jarvis
Congratulations to Ms. Rachel Jarvis on her recently accepted IEEE TIM paper titled "Application of Adaptive Pulse Compression in Cluttered Radar Cross Section Measurements." This article discusses a post-processing method, based on the reiterative minimum mean-squared-error (RMMSE) adaptive pulse compression (APC) algorithm, to achieve highly accurate radar cross section (RCS) measurements in challenging test environments. To validate the concept, the RCS of a 15.2 cm sphere is extracted in two measurement configurations (with and without a large nearby dominating scatterer). Implementation of APC in post-processing yields a 71.2% improvement in average RCS error compared to traditional processing in the sphere-only measurement and an 88.2% improvement in the presence of a metal plate. Congratulations, Ms. Jarvis, on this seminal contribution!

IEEE Access Paper Accepted - Led by Ms. Rachel Jarvis
Congratulations to Ms. Rachel Jarvis on her recently accepted IEEE Access paper titled "Methodology and Techniques for Highly-Precise Radar Cross Section Measurements at W-Band." In summary, this explores the challenges of radar cross section (RCS) measurements at W-band and proposes several techniques to overcome these challenges to obtain an accurate RCS measurement. The RCS of a 2.54 cm sphere is extracted with only 0.304 dBsm average error across the 80-90 GHz frequency range. Moreover, the average error of a distributed target consisting of four 2.54 cm spheres was extracted with 1.60 dBsm of average error, which was made possible due to precise laser alignment. Congratulations, Ms. Jarvis, on yet another excellent scholarly contribution!
