ARMOR Doppler Weather Radar

ARMOR (Advanced Radar for Meteorological and Operational Research) Doppler weather radar is one of the most advanced radar systems in the world. It is located at the Huntsville International Airport in Huntsville, Alabama. The radar is a collaborative effort between WHNT-TV and the University of Alabama in Huntsville.

Historic

This radar was originally a National Weather Service (NWS) local warning radar (WSR-74C) installed in 1977. It was refurbished and upgraded to Pulse-Doppler capabilities in 1991. When the NEXRAD network replaced previous NWS radars, it was donated to the UAH Department of Atmospheric Science in 2002 and upgraded to dual-polarimetry using the SIGMET Antenna Mounted Receiver in the Fall 2004.[1]

Then Baron Radar division of Baron Services, Inc., Huntsville, AL, In, upgraded the transmitter in 2005 to a 350 kW solid state transmitter. In the Fall of 2006, a high performance Seavey dual-polarization antenna and Orbit pedestal were purchased for ARMOR by the same company and made fully functional by the end of October.[2]

ARMOR is the first dual polarimetric radar used in broadcast television news, and one of the first systems of its type open for educational use to a public university, The University of Alabama in Huntsville (UAH). Baron has, to date, installed all broadcast dual-polarization radars in the world.[3]

Description

ARMOR is a C-Band (5625 MHz) radar with a 1 degree resolution in azimuth. The pulse length can vary from 0.4 to 2.5 microseconds and its peak power is 350 kW. It transmits and receives Vertical and Horizontal polarized signals.[2]

The following is information about the radar and its advanced systems:

Users

In a unique partnership, this research radar is used by meteorologists at WHNT-TV for forecasting and on air severe weather coverage. ARMOR was the first dual polarimetric capable radar installed by a television station. The data received from the radar is continuously archived at the National Space Science and Technology Center at UAH for full volumetric and surveillance scans.

ARMOR also deploys a live feed to the Huntsville National Weather Service Office making it one of the first NWS offices to gain first hand experience with dual-pole radar. Currently the national NEXRAD radar network is set to be upgraded to dual-pole within the next 5 to 10 years.
