Basic knowledge of radar circulators

　　Radar circulators are important microwave devices widely used in radar systems. Its main function is to transmit electromagnetic waves in different directions, ensuring the stable and efficient operation of the radar system. The core component of a radar ring resonator is a ring-shaped body made of magnetic material, and through this structural design, the unidirectional transmission characteristics of electromagnetic waves can be achieved.

　　In a radar system, the function of a ring resonator is to isolate the high-frequency signal generated by the transmitter from the echo signal received by the receiver, preventing mutual interference between the two. This isolation function not only improves the performance of the radar system, but also extends the service life of the equipment. In addition, radar circulators have the advantages of low insertion loss and high power capacity, making them a key component in modern radar systems.
