In this more cost-effective, less elaborate method, the disintegration time is calculated from a predetermined muzzle velocity and a distance to the target and is transmitted to a receiver coil prior to firing. The receiver coil is connected via a comparat or circuit (7) and a decoder (6) with a shift register (9), whose output is connected to a first comparator (6), so that the disintegration time is present on the outputs of the latter. A firs t counter (1), which is connected with a clock generator (2) and a programmable counter (3), is unblocked or blocked by the start-stop pulses, supplied via the receiver coil, of a muzzl e velocity measuring device. The programmable counter (3) forms a clock signal from the number of the clock pulses, added in the first counter (1) during the unblocked time, and of the clock generator frequency, whose frequency is equal to the muzzle velocity and is supplied via a binary circuit (4) to a second counter (5). The output of the second counter (5) is connected with the first comparator (6), wherein a firing signal (Z) appears at the output of the first capacitor (6) when the counter reading of the second counter (5) and the reading of the shift register (9) are the same.
