The Shared Mobile Atmospheric Research and Teaching Radar, colloquially known as SMART-R or SR, is a mobile Doppler weather radar platform operated and created by University of Oklahoma (OU) with aide from Texas A&M and Texas Tech University in 2001.

These two radars, both operating in the C-band, are less susceptible to attenuation in precipitation and have overall greater ranges for doppler products.

During development, a fire in the garage housing SR-1 broke out, destroying the truck and several components.

[4] Both SMART-Rs have sampled tornadic supercells across the plains, taking part in projects such as VORTEX-2 and VORTEX-SE.

Given the SR platform consists of two individual radars, projects are often arranged in what is known as a dual-doppler setup, whereas two radars are located at different locations in varying orientations so as to maximize wind retrieval accuracy.
