Abstract

An inductive or capacitative programming of a projectile is disclosed. A waveguide is used for the programming, the electromagnetic field being concentrated in the waveguide. The used programming unit includes at least one waveguide which is preferable located and/or integrated in the region of the muzzle, for example in front of the muzzle brake. A transmission coupler for the transmission is fed by a signal generator. The information relating to the projectile is modulated to the carrier frequency in the modulator. A reception coupler integrated on/in the projectile is electrically interconnected to a store or processor in the projectile. The reception coupler receives the modulated signal and transmits it to the processor which is where the eventual programming takes place.

Claims (18)

1. A method for programming a projectile during passage through a gun barrel and/or a muzzle brake, via a programming unit, the method comprising:

generating, via a signal generator, a carrier frequency that is adapted for the programming of the projectile;

impressing the generated carrier frequency upon the projectile during the passage of the projectile through the gun barrel and/or the muzzle brake, wherein information for the programming has been modulated onto the carrier frequency; and

performing the programming during passage through a waveguide that is operated below a cutoff frequency of the applicable waveguide mode.

2. The method according to claim 1 , wherein a V 0 measurement of the projectile takes place in the waveguide via a frequency generated for the measurement, the measurement taking place chronologically before the programming.

3. The method according to claim 2 , wherein an appropriate electromagnetic field is excited in the waveguide so that the frequency is reflected at the projectile and analyzed.

4. The method according to claim 1 , wherein an energy transmission to the projectile takes place in the waveguide via a frequency generated for the energy transmission.

5. The method according to claim 1 , wherein the frequency is greater than 0 Hz.

6. A device for programming a projectile during passage through a gun barrel and/or muzzle brake, the device comprising:

a programming unit comprising at least one waveguide that is the gun barrel, the muzzle brake, or an additional part between an end of the gun barrel and a start of a muzzle brake, or is additionally attached to the end of the muzzle brake;

at least one transmitting coupler that is supplied with a carrier frequency by a signal generator;

at least one modulator, in which the information provided for the projectile is modulated onto the carrier frequency; and

at least one receiving coupler incorporated on or in the projectile that is electrically connected to a storage device or processor in the projectile.

7. The device according to claim 6 , wherein the receiving coupler is a coil on the projectile, a dipole incorporated into/on the projectile, and/or a slot antenna.

8. The device according to claim 6 , wherein a receiving coupler and a receiving device connectable to the coupler are additionally incorporated, the signal of which is usable as a test signal for testing the programming.

9. The device according to claim 8 , wherein components for a V 0 measurement and/or an energy transmission are incorporated ahead of the programming device, the components including a common waveguide.

10. The device according to claim 9 , wherein the projectile has a sensor for the energy transmission that receives the signal with the frequency from the signal generator and charges a storage device in the projectile.

11. The device according to claim 9 , wherein components for the V 0 measurement and/or an energy transmission, include transmitting couplers, receiving couplers, and signal generators of a measurement device and/or an energy transmission unit.
