Method for correction of the detonation time of a projectile which is fired from a weapon barrel, and a circuit arrangement for carrying out the method

摘要

A method is described for correction of the detonation time of a projectile which is fired from a barrel, by means of a device for determining and evaluating the Doppler effect on microwave radiation which is emitted from the weapon barrel at a specific transmission frequency, to be precise using the formula <IMAGE> where S = distance, c = the speed of light, fo = transmission frequency from the weapon barrel fD = Doppler frequency According to the invention, the device measures the actual projectile speed profile with respect to time only for a specific time duration after firing and, outside this time duration, especially after it, the further speed profile is extrapolated. When the distance of flight determined in this way reaches a desired value, the detonation is triggered. The method is used whenever, for tactical reasons, the microwave radiation is emitted, for only a specific time after the firing, to the projectile, or whenever the signal received from the projectile falls below a specific level. <IMAGE>
