Intended for use where portability is essential, U.S. Army the lightweight and special divisions interim sensor (LSDIS) is a air defense artillery tactical radar, built by Lockheed Sanders in response to a 1991 contract.[1] It integrates with the Forward Area Air Defense (FAAD) system.

It can be carried by several soldiers and moved by a HMMWV light truck. Physically, it is a 4x8 foot array, mounted on a tripod. Its transmitter operates in the L band with 50 watts peak power.

This radar is part of a Ground-based Sense-and-Avoid Display System (SAVDS) for unmanned aerial vehicles.[2]
