Throughout the domain of sensors, the knowledge of the object signature (real or simulated) is primordial to understand the detection, reconnaissance and identification performances of these sensors. Although sensors in the radar domain (mostly active) and sensors in the optronics domain (mostly passive) rely on different working principles, the importance of the object signature within the chain of the sensor system is comparable. In optronics, research is conducted in the area of target detection, with application to drone detection and target masking using camouflage nets. Research is also conducted in the use of laser as non-lethal weapon, and amongst others, to blind cameras.
