1. An anti-drone method, the method comprising:
injecting a first GPS spoofing signal into a target drone;
observing a behavior of the target drone in response to the first GPS spoofing signal;
identifying and analyzing a feature of the target drone based on the behavior of the target drone, wherein a feature comprises a safety device mechanism or a path-following algorithm;
selecting a drone hijacking strategy from a database of predefined drone hijacking strategies based on the feature, and
hijacking the target drone by injecting a second GPS spoofing signal into the target drone based on the drone hijacking strategy corresponding to the analyzed drone feature among the predefined drone hijacking strategies.
