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.

Optical guide beam steering for projectiles

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.

Laser scanning device for fastest possible deflection or sweep velocities

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.

Guide beam and tracking system

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.

A system for automatically firing or discharing a weapon, such as a mine, comprises acoustical sensors for the preliminary adjustment and firing of the weapon. An optical sensor is used in conjunction with the acoustical sensors. In a first step, prior to the first acoustical target acquisition, the target background is optically scanned to store first optical image values defining an optical image of the target background to determine a firing range and a firing horizon. Thereafter, an acoustical ranging is performed for the target acquisition. Then the optical scanning and storing is repeated with regard to a firing horizon and when a target approaches the firing horizon, to provide second optical image values which are compared with the first image values to provide, by signal differentiation, proof of the presence of a target at the firing horizon. The resulting signal is used to control the weapon. The steps of optical scanning, signal storing, and comparing may be repeated for a target zone, which is larger than the target, whereby a target profile or silhouette is produced. The respective electrical signal is used for the fine adjustment of the weapon prior to firing by the target presence signal.
