Abstract: In an optical beam riding guidance for missiles according to the beam rider method, a definite recognition of the roll attitude and the location assignment is carried out in dependence on the expiring time in a simple manner and without previous synchronization with the launching installation.

Abstract: An ignition device for a projectile, in particular a guided missile, where the ignition moment is controllable as a function of the impingement delay and of the flight time of the projectile. This allows compensation for the type of material comprising the taget, e.g., hard or soft, and for the amount of time the projectile has been airborne, thus compensating for reduced projectile velocity at the time of striking the target.

Abstract: A laser scanning device for fastest possible deflection or sweep velocities s constructed for use in a laser guide or pilot beam system. The scanning device has two symmetric scanning cylinders which each are caused to rotate about their respective rotational axis or axis of symmetry by a gas stream so as to achieve a rapid beam deflection. Due to the low structural weight and small dimensions of the scanning cylinders with their respective scanning mirrors passing through the scanning cylinder at a slant, angular velocities up to the breaking limit of the material can be achieved.

Abstract: A guide beam and tracking system for acquiring a target and for guiding a ying body into the target operates in accordance with the beam rider principle. A tracking laser beam is imaged into the path of a guide laser beam so that both beams travel through the same optical devices and through the same deflection device. All components of the system, except the receiver are controlled by a central processing unit which may control one, two, or three laser generators to produce, in timed sequence, laser beams for different purposes. A highly precise target acquisition and a precise target tracking is achieved.

Abstract: A guide beam and tracking system for steering a flying body toward a target n accordance with the beam rider principle, is constructed for use under adverse weather conditions. Even under such adverse weather conditions a highly accurate target acquisition is assured due to the use of optical conversion, and beam expansion in the transmitter path, and heterodyning in the laser receiver. It is thus possible to achieve in addition to the highly accurate target acquisition, an accurate tracking of a flying body moving toward a target, under the control of a guide beam device.
