Abstract

A radar station antenna position control device for complex ship defense system comprises a transceiver antenna with radar station electronic equipment, which are connected by a high-frequency waveguide transmission line having multiline rotating and pilot-type couplings, swing and rotation drives; said drives comprise electric motors with mechanical transmissions, reducing gears and limit stops. The antenna turning according heeling angle (rolling motion) is made by turning the antenna post at the angle of ± 17°, position angle turning () at the angle of -10° to +60° and thereof rotation in parallel plane (azimuth position or relative bearing) without angle limitations is made by turning or rotation of the antenna in different planes; the heeling and azimuth rotation mechanisms are combined in a single assembly having double bearing made as a double cylinder with a mechanism for transformation of translational displacement into rotation motion which made as rail pairs, the turn and rotation drives has and s; as actuation elements synchronous electric motors with constant magnets at rotor axes are used, with pulse-duration control of rotation frequency; herein, for angle turning according position () the rail transmission with a resilient torque member is used, the latter is used to take up the backlash in the rail transmission, and is built in the lateral rotating part of antenna body, as sensors of output axis tuning angle electrooptical angle sensors-encoders are used, issuing an output data signal in digital format, to provide free passage of high-frequency wave-guide transmission line having multiline rotating and pilot-type couplings of stabilizing drive axis (according rolling and pitching motion and relative bearing rotation) are performed hollow, as an external information source signals of a ship biplanar roll meter is used.
