Abstract: In order to determine crosswind effects between a weapon and its intended target (204) a crosswind gradient measuring apparatus (600) directs a first pulsed coherent light beam (646) and a second pulsed coherent light beam (648) to the target (204). Light of both beams scattered back by aerosols in the air is measured by using a detector (652) thus generating a beat frequency in the detector signal. The beat frequency indicates a Doppler-shift due to crosswind as a function of range between weapon and target wherein the range is determined by the time of flight. The information determined by such a Doppler differential interferometer, DDI, is utilised by a signal processor (608) to calculate the bullet's crosswind offset which enables manual of automatic adjustment of an aiming mechanism.

Abstract: The aim of the invention is to devise an inexpensive method and device that allows predefined target tolerances of an automatic weapon (1) to be maintained even in the range of prevailing resonant cadences. This aim is achieved by modifying the actual cadence of the automatic weapon from shot to shot around a predefined cadence lying within the range of a resonant cadence so that the time interval between successively triggered shots is alternately shorter and longer than the calculated constant time interval between the individual triggered shots that is calculated for the predefined cadence and that corresponds to the constant time interval required to fire the automatic weapon at the predefined cadence. In this way, the automatic weapon is controlled to fire at a time averaged cadence that is equal to the desired predefined cadence while avoiding ever actually firing the automatic weapon, shot-by-shot, at the resonant cadence.

Abstract: A Reconfigurable Nose Control System (RNCS) is designed to adjust the flight path of spin-stabilized artillery projectiles. The RNCS uses the surface of a projectile nose cone as a trim tab. The nose cone may be despun by the action of aerodynamic surfaces, to zero spin relative to earth fixed coordinates using local air flow, and deflected by a simple rotary motion of a Divert Motor about the longitudinal axis of the projectile. A forward section of the nose cone having an ogive is mounted at an angle to the longitudinal axis of the projectile, forming an axial offset of an axis of the forward section with respect to the longitudinal axis of the projectile. Another section of the nose cone includes another motor, the Roll Generator Motor, that is rotationally decoupled from the forward section and rotates the deflected forward section so that its axis may be pointed in any direction within its range of motion.

Abstract: A weather resistant modular sensor and computing platform reduces costs and enhances versatility of sensor systems. Rapidly evolving electronic technology results in hyper-obsolescence wherein sensor systems that are state of the art technology when designed, fall behind the art quickly as new transducers, batteries and components are developed.

Modularity and low cost manufacturing methods enable the practical definition of a cylindrical computer. The cylinder shaped enclosures have on their ends a common connection interface to which modules may be added. This provides a long system life cycle and wide ranging versatility. The size of the platform is not restricted.

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.
