Surface moving target indication (SMTI) involves searching Earth's surface for moving objects using a dedicated radar mode. Ground-moving target indication (GMTI) is a subordinate, commonly referenced mode implying the detection, location, and discrimination of vehicles and personnel (dismounts) against rural, suburban, and urban land settings. The general class of SMTI radar modes also includes searching for vessels against sea, lake, and riverine backgrounds. An SMTI platform can be an aircraft, an unmanned aerial system (UAS), a satellite, an aerostat, or a tower.
