MULTIFUNCTIONAL OPTICAL-RADAR SYSTEM Russian patent published in 2007 - IPC G01S17/00 

FIELD: laser detection and ranging of objects.

SUBSTANCE: optic-radar system has the following members which are disposed on optical axis of transmitting channel and optically conjugated: laser transmitter to form probing beam of laser radiation, pilot laser to form control beam of laser radiation; beam splitters, forming telescope, Dove prism, device to reflect laser radiation beam, output telescope, horizontal platform which has first and second mirrors disposed onto it, which platform is made for rotation around vertical axis, three coaxial shafts of rotation. System also has third mirror optically conjugated with back reflecting side of first mirror, mirror-lens objective of receiving telescope, angle mirror, and combined photo-receiving unit. Second and third mirrors are made for synchronous rotation about horizontal axis. System also has adjusting unit which has rectangular prism in center of first mirror, rectangular reflecting prisms in centers of second and third mirrors, prism-rhomb with diaphragm mounted onto output face of prism-rhomb, and signal processing units, drives, current condition detectors and control units of optical-mechanical units of system, and central control unit.

EFFECT: reduced weight; simplified design; improved precision of range finding and detection; widened range of optical-electronic means of detection of moving objects; improved precision of measurement of speed of moving objects.
