[0002] Radar is an electronic system that uses radio waves to detect and determine the target's position, distance, movement speed and direction. Guidance radar is used to detect and accurately measure aerial targets and their coordinates within the detection range. It is an air intelligence radar that is responsible for guidance and interception missions.

[0003] However, in the existing technology, the existing commonly used radar is fixed on an iron frame, and when installing the radar antenna, a wrench needs to be used to tighten the bolt knob to achieve its installation, and it is troublesome to disassemble the radar antenna. After the radar antenna is installed, the wind blows on its surface outdoors, which will cause the equipment to vibrate, and even cause the parts on the equipment to loosen due to bumps. Without better buffering protection measures, the radar antenna fastened on the iron frame is not easy to adjust and is not easy to receive signals better.

[0004] Therefore, we need a broadband frequency source for radar seeker, which can solve the problem of stable installation of existing radar antenna and also realize the installation adjustment and replacement of receiving signal frequency of radar antenna. Utility Model Content
