Radar

Radar is an object-detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish or antenna transmits pulses of radio...

s (AN/MPQ64 Sentinel), one fire control centre (CTOC), one electro-optical camera vehicle (MSP500) and one Tactical Control Cell (TCC) vehicle.

The upgrades consists of:

• New radars, which can be mounted on a variety of vehicles. The radars have their own power supply and can process and distribute the data independently. The vehicles can be connected via radio links, cable, through Multi Rolle Radio

• The radars have a larger frequency spectrum and variable rotation speeds, and also an increased capacity to spot and follow targets.
• Each module can automatically define its position with its northfinder and GPS instruments.
• The control centre modules can be mounted on a large variety of vehicles
• The electro-optical MSP500 sensor is equipped with a laser range finder and a TV-camera, as well as an upgraded IR-camera. These can be used to fire the missiles passively, which has been successfully tested.

The control system can detach itself from the sensors, in order to become less visible.
