The role of fiber optic gyroscope in radar antenna positioning system is to improve the accuracy and reliability of navigation system, and it also has the characteristics of fast response, vibration resistance and uninterrupted operation. Fiber optic gyroscope is an instrument that can accurately determine the orientation of moving objects. It is mainly composed of light source, beam splitter, fiber optic loop and detector. Its working principle is to use the influence of rotation signal on the optical path difference of two relative sensors to infer the rotation angular velocity of the object. When light flows through two circular fiber paths in the same direction, the rotation of the circular light path will cause the counterclockwise and clockwise light to propagate along different paths, forming a phase difference. This phase difference is proportional to the rotation rate, so as to measure the rotation speed of the object. Fiber optic gyroscope is widely used in inertial navigation, ship attitude control and other fields, which can improve the accuracy and reliability of navigation system. It also has important application value in seismic exploration, measurement and detection. Especially in radar antenna positioning system, the application of fiber optic gyroscope can significantly improve the performance of the system.

‌Radar antenna positioning systems rely on precise navigation and positioning data, and the high-precision angular velocity and direction detection provided by fiber optic gyroscopes can ensure the accurate pointing and positioning of radar antennas, thereby improving the overall performance and reliability of radar systems. ‌In addition, the fast response, vibration resistance and uninterrupted operation of fiber optic gyroscopes also enable radar antenna positioning systems to maintain stable performance in complex environments or dynamic conditions, especially in extremely harsh environments such as wind, sand, and heavy rain.
