Description

technical field [0001] The invention relates to the technical field of detection and positioning, in particular to a detection and positioning system and method for an unmanned aerial vehicle. Background technique [0002] With the advancement of science and technology, micro-UAVs have been widely used in fields such as aerial photography, remote monitoring, and aircraft model hobbies. In recent years, incidents such as micro-UAVs intruding into the airspace of government departments, national air defense airspace, and civil / military airport clearance areas have occurred many times, resulting in serious safety hazards. Therefore, solving the detection and positioning of micro-UAVs has been achieved. received widespread attention. [0003] At present, the UAV positioning system mainly includes an active radar system and a passive detection system. The passive detection system uses the reflection or scattering of the external radiation source signal to detect and locate the U...

AI Technical Summary

Problems solved by technology

[0004] However, the passive detection system can detect and locate the UAV only when there is a signal from the external radiation source, and the reflection area of ​​the micro UAV is small, which will reduce the detection and positioning accuracy of the UAV
