Abstract
A laser radar-proximity fuse with a laser-range measuring device and mask or camouflage discrimination, wherein for the initiation of the fuse, is no longer triggered at the beginning rather but at the end of an echo pulse configuration, even though its comparatively flat descending or falling pulse flank is or is not adapted for the determination of a clear, reproducible or controllable triggering point-in-time. By applying a Constant-Fraction-Trigger-Principle, which has heretofore been applied primarily to the rising or ascending flank of a pulse, there can be also derived a good controllable range or distance-dependent triggering pulse for the thereby optimized initiation of the fuse from the flatter rear flank of the echo pulse configuration, whereby the attacking of the target will not take place prematurely, but will be better directed toward the target center.
