3D GSR is a short-rang battlefield radar for detection, acquisition, localization and recognition of targets (pedestrians, light vehicles, tanks/trucks, light aircraft and helicopters), either on or near the ground in all weathers.
GSR can  be available in three versions: man portable and broken down into several parts, shelter-mounted and vehicle-mounted.
Analysis of battlefield conditions allows to divide information problems, arising during combat operations in defense, attacks, any weather conditions in the day and night time, into classes depending on dimensions (range and azimuth) of the scanned area and the required accuracy target coordinate setting.
The solution of every problem class can be done most effectively by creating and using of a number of radar modifications the main performances of which are specified below.
The complete list of requirements and some  performance specifications of ground target reconnaissance radars should be discussed and revised together with the Customer in order to make them more accurate.
Radar tactics of such a class in attacks by friendly units requires detecting and discrimination of fixed targets of a defender-unit. Such targets may be represented by dig-in tanks, stationary fortifications, anti-tank guns, etc.
Radars of such class must have high mobility, short deployment, high reliability, intelligent interface and provide radar security.
