Optoelectronic slip rings, which can stably transmit optical signals and electrical power, as well as they have long working life and high reliability. So the slip ring have become an indispensable core component in modern high-performance radars, especially large radars, warning and guidance radars, laser radars. Here are a few specific application examples as following.
Airborne/spaceborne synthetic aperture radar
SAR systems need to process massive amounts of raw echo data with extremely high data rates. Through the photoelectric combination slip ring, radar data from rotating platforms such as satellite antennas and drone rotors can be transmitted in real-time and without error to the recording and processing system on fixed platforms, which is a key guarantee for achieving high-resolution radar imaging.
Large land-based phased array early warning radar
This type of radar antenna has a huge array and requires rotating scanning. The control signals and status monitoring data of thousands of T/R modules on the array are enormous, and powerful power needs to be provided for them. The photoelectric slip ring uses optical fibers to transmit all control and data signals, while the electric slip ring transmits high voltage and high current, which is the core supporting its stable operation.
Shipborne multifunctional radar
The electromagnetic interference in the ship environment is complex and the space is compact. The photoelectric combination slip ring not only resists interference from other high-power equipment on board, but also has the characteristics of small size and lightweight, which is very suitable for the limited space layout of ships, providing stable and reliable all-round scanning capability for shipborne radar.
Fire control radar and tracking radar
This type of radar requires fast response speed and high data update rate. The high-speed and low latency characteristics of the fiber electrical slip ring ensure that target information can be exchanged in near real time between the rotating antenna and the central processor, greatly improving the tracking accuracy and response speed of the system.
