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...
