System and method for detecting and defending drones

Abstract

The invention discloses an unmanned aerial vehicle detection and defense system, which comprises a central management platform, a gateway system, an air defense early warning and tracking system and an interference countermeasure system. The central management platform is respectively connected with the air defense early warning and tracking system and the interference countermeasure system through the gateway system. The air defense early warning and tracking system comprises a spectrum detection device and an optoelectronic detection device, which are used for detecting the characteristic information of moving targets in the area. The jamming countermeasure system comprises a cloud platform jamming device and a base station jamming device, which are used for driving off and landing the intrusion target; the gateway system is used for sending the characteristic information to the gateway program to obtain the alarm information. The central management platform displays the dynamic information of UAV in real time according to the alarm information and accepts the control instruction sent by the user. The invention adopts frequency spectrum detection, combines with photoelectricity to carry out tracking, controls interference countermeasure system to emit interference electromagnetic through central management platform, achieves interference effect, realizes positioning and tracking, and improves interception success rate.

Description

technical field [0001] The invention relates to the research field of unmanned aerial vehicle technology, in particular to an unmanned aerial vehicle detection and defense system and method. Background technique [0002] With the continuous development of drone technology in recent years, drones have been widely used in many civilian fields due to their small size, low cost, and convenient use, especially consumer drones. The popularization in the middle is followed by serious low-altitude safety hazards. The existing interception methods for UAVs mainly include projectile interception, net interception and radio frequency suppression. Among them, projectile interception and net interception have a short distance and a low success rate; radio frequency suppression is not flexible enough to locate and track UAVs. Contents of the invention [0003] The main purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a UAV ...
