Abstract

The invention relates to a photoelectric composite cable for radar. The cable is connected between a radar antenna and a radar control center and used for transmitting electric signals and optical signals, and the photoelectric composite cable for the radar comprises a cable core and an outer sheath coated outside the cable core. A shielding layer is arranged between the cable core and the outer sheath, the cable core comprises a power source unit, an optical unit and a data unit, the power source unit comprises three power lines, the optical unit comprises a plurality of single mode optical fibers, a waterproof layer coated outside the single mode optical fibers and an optical unit protection layer coated outside the waterproof layer, the data unit comprises a plurality of data line pairs, and the shielding layer comprises an inner shielding layer coated outside the cable core and an outer shielding layer coated outside the inner shielding layer. Bilayer shielding is arranged, so that shielding effects are good, and interferences of electromagnetic waves can be effectively avoided; and the single mode optical fibers are used for transmitting the optical signals, so that transmission loss is small and transmission distance is long under high frequency, remote control of the radar antenna can be realized, and the photoelectric composite cable for the radar is applicable to different service environments.

Description

technical field [0001] The invention relates to a photoelectric composite cable suitable for transmitting signals between a radar antenna and a radar control center. Background technique [0002] Radar is an electronic device that uses electromagnetic waves to detect targets. It emits electromagnetic waves to irradiate the target and receives its echoes, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the distance change rate (radial velocity), azimuth, and height. The use in the military field is already a very mature technology. [0003] Traditional radar cables use coaxial cables to connect the radar antenna and the radar control command center. Due to the high-frequency transmission problem of the coaxial cable, the radar antenna must be very close to the radar control center. Once the radar antenna is damaged, it will affect the control center and eventually lead to the destruction of the entire radar syste...
