Laser beam rider guidance utilizing beam quadrature detection

摘要

A beam rider guidance system is presented which uses a rotating laser light pattern to enable a weapon-borne laser receiver to derive its position relative to the beam axis. The guidance beam consists of changing light patterns detected and decoded by the receiver as a guidance code, which defines the unique weapon position in the beam. The code is composed of four distinguishable patterns of light bars which can be detected and decoded into electrical pulses by the laser receiver located anywhere within the confines by the guidance beam.
