Abstract: An artillery shell radar system is disclosed including an antenna directed off axis to produce, in conjunction with the spin of the artillery shell, a conical scan of the target area, with the off axis angle being adjustable by changing the phase shift used in a phased array. Radiation reflected from the target after transmission by a transmitter within the artillery shell is processed to detect and select a target whose position is used to guide the artillery shell by adjustment of guide fins. Gyroscopic inertial navigation equipment and ECM detection may be included.

Abstract: The present invention relates to means for reducing the gun firing dispersion in a weapon system. The gun (4) comprises a gun servo for aiming the gun at a target. A programmable signal generator (5) is arranged to produce a damping signal (z) which is supplied to the gun servo system at the firing of the gun and which signal has such a character that the oscillating movements which are generated at the firing of the gun are counteracted. A recoil sensor (6) is provided for sensing the start of the recoil movements of the gun and emitting a trigging pulse to the signal generator (5) which in turn is producing said damping signal (z) preferably in the form of a pulse train in which the number of pulses, the pulse widths, polarities and amplitudes of individual pulses can be varied and which has a certain time relationship with the gun firing moment.

Abstract: The position, velocity or acceleration of a weapon in traverse and/or elevation is maintained constant at its value just prior to firing of the weapon, for a short period including the firing, thereby minimizing operator errors in aiming caused by smoke and vibration.
