About me

I am a senior research scientist with the Cooperative Institute for Mesoscale Meteorological Studies (CIMMS) and the Advanced Radar Research Center (ARRC) at the University of Oklahoma (OU), where I am affiliated with the National Severe Storms Laboratory (NSSL).

My background is in electrical engineering, and I have over 15 years of experience in the field of weather radar signal processing. I am the leader of the Advanced Radar Techniques (ART) team within the Radar Research and Development Division at NSSL where I work on:

Hot Item: Multifunction on NSSL's Phased-Array Radar

In order to demonstrate the multifunction capabilities of a phased-array radar (PAR) system, an aircraft-detection-and-tracking module was designed and implemented on the National Weather Radar Testbed (NWRT) PAR in real-time.

Notional integrated weather and aircraft tracking display

Combining weather and aviation functions involves meeting several demanding requirements including sensitivity, coverage, data quality, spatial resolution, and temporal resolution.

In general, power-aperture, bandwidth, and time can be traded in many different ways to achieve multifunction, but this remains one of the main challenges in the design of an affordable MPAR system. The goal here is not to provide a prototype for an MPAR system, but to use the existing PAR (with its many limitations) as a proof of concept for multifunction and establish a framework for future research.

Please follow the link below to read more about the first steps taken at NSSL to upgrade the NWRT PAR in order to demonstrate a combination of weather and terminal aviation functions.
