Slip ring is a key component of radar antenna. It can make the rotating part and the fixed part of the radar keep continuous transmission of power and signals while rotating 360 degrees. The specific uses and structures of radar are different, but the basic forms are the same, including transmitter, transmitting antenna, receiver, receiving antenna, processor and display. There are power supply equipment, data acquisition equipment, anti-interference equipment and other auxiliary equipment. According to the form of radar signal, there are pulse radar, continuous wave radar, pulse compression radar and frequency agile radar.

    Slip rings, also known as rotary electrical interfaces and electrical rotating joints, can be used in any system that requires unlimited continuous rotation to transmit power and data signals from a fixed structure to a rotating structure.
