Dog Ear

The Dog Ear (with the Russian designation of 9S80) is a Russian ground-based, target-acquisition radar mounted on an MT-LB multi-purpose tracked vehicle or MT-LBu armored command and reconnaissance vehicle (ACRV). It uses an open-mesh, rounded-rectangle parabolic antenna. 

The radar supplies target alerting information to the SA-13 Gopher (Russian 9K35 Strela-10) surface-to-air missile (SAM) system. Deployment usually involves one system for each air defense battery/battalion.

In service.

The Dog Ear is in service with SA-13 Gopher SAM batteries. In some cases, upgraded SA-13 systems may have replaced the Dog Ear.

Production reportedly began in 1983.
