Radar Rotary Joints with Contactless Data Transmission

In the radar technology sector, the trend towards installing active components directly on the antenna is continuing.

The radical reduction in cabling saves weight and increases the efficiency of the system. However, ever increasing amounts of data with high transmission rates also require demanding digital data transmission solutions.

For radar rotary joints, this means that traditional HF modules for the different frequency bands are replaced by diverse media couplers, power current and signal transmission paths.

The hybrid rotary joint shown in the picture does not include any traditional RF rotary joint. Various contactless data transmission systems are used to control the radar transceivers on the rotating platform.
