An interlocking control device for scientific research ship weather radar and satellite c-antenna

Abstract

The invention discloses a weather radar and satellite communication C antenna interlocking control device for scientific research ship, which includes a radar mast, a weather radar antenna and controller, two satellite C antennas and controllers, several satellite communication C and weather radars Operation status display and alarm board, several power supplies, communication and control cables, weather radar air-to-air calibration and detection requires the antenna to be unobstructed and has a high transmission power, and Satcom C’s air-to-air sending and receiving navigation information also requires the antenna to be unobstructed and easily damaged Signal interference, the two have conflicts in spatial arrangement and signal electromagnetic compatibility. The present invention installs the weather radar antenna at the highest possible point of the radar mast, and wherein a set of satellite communication C antenna is installed on the top of the weather radar antenna. The satellite communication C and The signal transmission between the weather radar controllers realizes the control chain of the two systems, which not only avoids the danger of Satcom C antenna being damaged by the weather radar antenna, but also ensures the effectiveness and accuracy of the weather radar in air calibration and detection.

Description

technical field [0001] The invention relates to a scientific research ship weather radar and a satellite communication C antenna chain control device, belonging to the technical field of ship design and manufacture. Background technique [0002] With the deepening of marine meteorological research, the demand for installing meteorological radars on comprehensive scientific research ships has gradually increased. Due to the improvement of the detection distance and accuracy requirements of the weather radar, the transmitted pulse power is relatively large. During operation, the pointing angle or pitch angle should be adjusted, and the azimuth should be rotated 360°. The antenna is required to be unobstructed, and it is easy to detect the surrounding radio. The usual solution for damage to communications equipment is to mount the weather radar higher on the radar mast and keep other communications antennas away from their transmit beam angles. As an important device of GMDSS,...
