A method and apparatus for determining the roll angle position of a rotating flying body (2) relative to a fixed station (1) with the aid of a laser (3) light beam (4, 24) emitted by the fixed station (1) and received by the flying body (2). To determine the roll angle position of the flying body located at an arbitrary position within the guide beam (4) precisely and simply, a phase-coded laser light beam (guide beam) is produced with the aid of an optical element, particularly a holographic optical element (6). This guide beam (14) is then decoded in a receiving apparatus (8) of the flying body by means of a further holographic element (11) that is rigidly connected to the flying body (2). The further holographic element (11) is configured such that maximum brightness or intensity only occurs at the receiving detector (13) if it is located parallel to the holographic element (11) on the side of the laser (3), i.e., non-mirror-symmetric information must be impressed upon the guide beam (4).

Method and apparatus for determining the roll angle position of a

An apparatus for flight path correction of flying bodies, such as projectiles, rockets and the like, with the aid of a laser guide beam, wherein the course of the respective flying body is determined and processed in a measuring apparatus associated with the firing apparatus and containing an optical receiving detector in order to obtain an appropriate correction signal, and wherein the correction signal is then transmitted, through encoding of the laser guide beam, to a receiving apparatus disposed in the tail portion of the flying body. To determine the course of the flying body in a simple manner, both an optical light source for producing a light beam and an optical receiving detector are disposed on the measuring apparatus, and triple reflector or mirror elements, that reflect the incident light beam back in its initial direction independently of the respective angle of incidence, are disposed on the bottom of the flying body or at the ends of the guiding mechanism of the flying body. In rotating flying bodies, the triple mirror elements are preferably distributed at irregular intervals in a circle, perpendicular to the longitudinal axis of the flying body. This arrangement makes it possible to use the signals reflected by the triple mirror elements to determine the roll position of the respective flying body.

Apparatus for flight path correction of flying bodies

A method and an apparatus for flight path correction of one or more projectiles (2-6) with the aid of a guide beam (9), wherein target data, such as speed, range and direction of movement, are continuously acquired in a fire-guidance system associated with the firing device (1), for example, an automatic cannon, and are transmitted to the laser apparatus (21) that produces the guide beam (9), and wherein each projectile includes a receiving apparatus (31) which receives the guide beam (9). To be able to correct, in a simple manner with a pulse correction, both individual projectiles as well as a plurality of projectiles flying closely behind one another in time and having different courses, the guide beam (9) is aimed toward the collision point (15) calculated on the basis of the target data, and the guide beam (9) is subdivided into a plurality, at least five, partial beams (guide beam segments 10-14) including a central guide beam segment (10) which is aimed at the collision point (15) and around which the remaining partial beams or beam segments are disposed. The guide beam segments (10-14) are all modulated differently. Each projectile (2-6), with the aid of its respective receiving apparatus (31), then determines the angular position necessary for the correction, with respect to the collision point (15), from the modulation of the respective received guide beam segment (10-14).
