  • Patent number: 7825850
    Abstract: It is proposed to use the gun barrel or launcher tube or the muzzle brake as a waveguide, which, however, is operated at a frequency that is below the cutoff frequency of the relevant waveguide mode. The transmit coupler excites the relevant waveguide mode. An oscillator generates the signal, which is then sent to the transmit coupler. The waveguide and the projectile form a system in which the electromagnetic field at the receive coupler is influenced by the position of the projectile. The characteristic change over time of the strength of the electromagnetic field at the location of the receive coupler that results from the change in the distance between the projectile and the receive coupler is measured and used to determine the muzzle velocity.

  • Publication number: 20040250615
    Abstract: A device (10) and a method for determining the muzzle velocity (V0) of the projectile (1) upon exiting a weapon barrel (11). The device (10) includes a coil (12), which is positioned around a longitudinal axis (11.1) of the weapon barrel (11) in the region before the exit, and a supply device (15) for impressing a current (I) in the coil (12) to generate a magnetic field (H). The device (10) additionally includes an analysis device (16), which reads off a voltage pulse on the coil (12), induced during the passage of the projectile (1) through the magnetic field of the coil (12). Two predetermined points of the voltage pulse are detected, the time interval between the two points is determined, and the muzzle velocity (V0) of the projectile (1) is calculated from the time interval.

  • Patent number: 6750806
    Abstract: A method of tracking a target (2) moving in an airspace and a target tracking system (10) for performing the method are described. A search sensor (12) searches a search space at a first clock rate (2&pgr;/&Dgr;T1) and establishes target information in regard to a track (4) flown through by the target (2). Calculation means (16) extrapolate an expected flight path (6) from the target information established and provide flight path data, which describes the expected flight path (8), to a tracking sensor (14), which covers a tracking space (15), and provides this data at a second clock rate (2&pgr;/&Dgr;T2), which is higher than the first clock rate (2&pgr;/&Dgr;T1). When the target (2) reaches the tracking space (15), the tracking sensor (14) is aimed at the expected flight path (6) on the basis of the flight path data provided, the target (2) is detected as soon as it is detectable by the tracking sensor (14), and the tracking sensor (14) is tracked on the target autonomously.

  • Publication number: 20030183070
    Abstract: A method and a device (20) are described for compensating firing errors of a gun having a weapon barrel (10.2). Firing errors, which are caused by static gun geometry errors, which influence the position of the weapon barrel (10.2) during aiming of the weapon barrel (10.2) at aiming values, are compensated. For this purpose, the weapon barrel (10.2) is brought into measurement positions in steps by rotation around an axis. Using suitable devices of a measurement facility, an intended value, which describes the intended position of the weapon barrel (10.2), and an actual value, which describes the actual position of the weapon barrel (10.2), are detected at each measurement position. A difference between the actual value and the intended value, defined as an error value, is then calculated. Correction values are established from multiple error values of the measurement positions and the correction values are taken into consideration during later aiming of the weapon barrel (10.2).

  • Patent number: 6556324
    Abstract: A device for the control of the beam alignment in satellite laser communications systems has a digital signal processor (24), which has been inserted between an input interface (21) and an output interface (23), and to which a program memory (25) and a data memory (26) are separately connected, in which parameters are also stored, and which comprises sensors (171, 172, 173) and actuators (174, 175, 176) for aligning the laser beam with the counter station. The signal processor (24) contains an intermediate memory (240) for floating point and fixed point operations and further calculating units (241, 242, 243), as well as two access generators (244, 245). Highly flexible and very efficient control systems can be implemented by the employment of such a digital signal processor. By means of an adaptive control it is still possible to operate beam alignment systems at full performance levels, even after components have been degraded.

  • Patent number: 6497171
    Abstract: The invention relates to a method and a device for the correction of dynamic gun errors. Dynamic gun errors are caused by the movement of a gun tube muzzle area (3) of a gun (1) in the course of continuous firing. To correct these errors, a measurement of the movement of a gun tube muzzle area (3) of a gun (1) is performed during continuous firing for obtaining measured signals. The measured signals are used for correcting the azimuth and elevation of the gun tube (2) in order to compensate the movement of a gun tube muzzle area (3).
