Nowadays, armored ground vehicles such as tanks have to face an increasing number of threats. For instance, helicopters have become important threats with mainly more and more improved locking-on mode and firing mode capabilities. Plus, new lightweight ground vehicles are current threats to deal with.

Consequently, Search Sights have to upgrade their detection, locking-on, tracking and identification capabilities to counter multiple threats on various backgrounds and atmospheric conditions (desert, landscape...). Currently, Infrared sensors are the main core of these Surveillance Systems. In most cases, an operator (tank chief) via a joystick manages them.

In this paper, a practical example of Search Sight Management for tanks associated with new automatic processes including operator information feedback is presented. The case studied here is a real-time implemented Semi-Automatic Search Infrared Sensor Suite.

The article provides also system performances resulting from Field Trials. They highlight the impact of the new function in the overall system reaction time.
