Ground-Level and Low-Speed
(Low-Flying) Target Detection Radar 111L1 "LIS"

111L1 Radar is designed for detection of moving people and vehicles (optionally – low-flying targets and maritime targets) for security and reconnaissance support.
Radar provides automatic detection and location of targets at any time of the year under conditions of rain, fog, precipitation, smoke or dust, in default of optical visibility. The targets are displayed on the LCD indicator together with bearing and range data.
During processing the non-parametric algorithms are applied, thus allowing to escape the false targets tracking regardless of interference environment. Target recognition mode allows to detect automatically target velocity and listen to the specific sound spectrum of a target (man, group, vehicle, helicopter etc.).
The basic version is designed to allow the radar installation on the horizontally adjustable platform. The version with the stabilized platform allows using radar as a vehicle-based (APC, ACV, automobile) fast-deployed mobile complex, featuring automatic antenna leveling according to the indications of the built-in accelerometer horizon sensors.
Antenna rotation and leveling is executed by piezoelectric, gearless, reversible electromotors.
