Instrument

TDR
Tail Doppler Radar

The Tail Doppler Radar (TDR) is an airborne vertically scanning, pulse Dopper X-band radar operated by NOAA. It is installed on the tail of the research aircraft and is typically equipped on NOAA’s P-3 aircraft for hurricane and precipitation research missions. TDR measures radar reflectivity and Doppler wind velocities at the 9315 MHz frequency band. It has a horizontal beam width of 1.35 degrees and a range gate spacing of 150 or 300 meters.
