Abstract
An ammunition unit includes an impact fuse for sensing the hardness of a target and, based on the sensed hardness, triggering a burst inside, at or outside the target. The impact fuze includes a first sensor for sensing soft targets having a first outer cone with a conductive inner surface and a first inner cone surrounded by the first outer cone having a conductive outer surface. These conductive inner surfaces come in contact with each other upon an impact of the ammunition unit against a soft target due to deformation of the outer cone towards the first inner cone. A second impact sensor for sensing hard targets includes a second inner cone with a conductive outer surface and the first inner cone having also a conductive inner surface and surrounding the second inner cone, the first inner cone being deformable or displaceable towards the second inner cone with the conductive surfaces coming into contact with each other upon impact against hard targets, but not during impact against a soft target. The first and second impact sensors are connected to at least one signal-processing circuit, wherein a first activating signal generated by the first sensor causes a delayed activation …
