The HARD 3D search and acquisition radar is installed on the platoon command post. HARD, supplied by Saab (formerly Ericsson) Microwave Systems, operates in the X band and has a range 20km. HARD has a MTI (moving target indicator) mode for fixed-wing targets, helicopter mode for helicopter detection and analysis and a non-MTI mode for increased sensitivity and detection of tangential targets. Data processing allows automatic track initiation on both targets and jammers. The radar uses a complex search beam pattern with multiple tracking beams in the target direction.
Target acquisition is achieved, either by the HARD radar, which downloads target data via radio data link to the Ozelot weapon platform, or by the Thales (formerly Pilkington) Optronics ADAD passive infrared search and track system (IRST), mounted on the forward part of the roof.
For target tracking, the Ozelot is equipped with its own stabilised forward-looking infrared (FLIR) sensor, TV and laser rangefinder as well as dual mode autotracking. The system is capable of automatic range and envelope determination and fire control and second shot capability on the same approaching target. Remote control at up to 100m is possible using the same control and display unit.
In addition to the weapon pedestal, there is a navigation system with a global positioning system (GPS), inertial navigation system and north-finding gyroscope, and the C31 interface via VHF-radio for data and voice transmission.
