Description

Technical Field

[0001] The present invention relates to a turntable, and more specifically to a large heavy-duty tracking turntable with a radar lifting platform. Background Art

[0002] As a high-precision azimuth rotation platform, the turntable is widely used in fields such as optoelectronic tracking and target recognition. Traditional optoelectronic turntables usually carry optical payloads, such as visible light cameras, infrared thermal imagers, etc., to achieve the detection, recognition, and tracking of targets. However, with the continuous improvement of the requirements for target detection capabilities in modern warfare, a single optoelectronic detection method is difficult to meet the needs in complex battlefield environments. Radar detection has advantages such as a long action range, strong anti-interference ability, and all-weather operation. Integrating radar and optoelectronic systems on the same turntable to achieve multi-sensor information fusion has become an important development direction for improving target detection capabilities.

[0003] However, the introduction of the radar lifting platform poses severe challenges to the turntable. First of all, the lifting platform itself and the radar antenna it carries are extremely heavy, resulting in a significant increase in the load borne by the turntable, which puts higher requirements on the bearing capacity, structural strength, and rigidity of the turntable. Secondly, the lifting movement of the lifting platform will cause the dynamic change of the center of gravity position of the turntable, thereby affecting the stability and movement accuracy of the turntable. In addition, the radar system will generate vibrations and shocks during operation, and these factors will further exacerbate the load on the turntable and may cause structural resonance, affecting the radar detection performance.

[0004] To solve the above problems, there is an urgent need for a radar lifting platform that can be used in conjunction with an optoelectronic turntable. This lifting platform needs to have the following characteristics: First, it can carry a large-sized and heavy radar antenna and has sufficient structural strength and stability; second, it can provide a large enough platform to realize the pitching movement of the radar antenna and cooperate with the azimuth rotation of the optoelectronic turntable to achieve the omnidirectional detection of the radar antenna; finally, it needs to reduce its own weight as much as possible and use lightweight materials and optimized structural designs to reduce the load on the optoelectronic turntable and avoid having too much impact on the performance of the turntable.

[0005] In summary, developing a radar lifting platform for an optoelectronic turntable is of great significance for improving target detection capabilities and achieving multi-sensor information fusion. Summary of the Invention

[0006] To overcome the deficiencies of the prior art, the present invention provides a large heavy-duty tracking turntable with a radar lifting platform, and its beneficial effect is to install a radar lifting platform on the optoelectronic turntable to improve target detection capabilities and achieve multi-sensor information fusion, and use a connecting frame to fixedly connect the radar lifting platform to the turntable box body to improve the overall structural stability and bearing capacity of the system.
