Classification: CPC G | IPC G

Claim 10:
11. A system comprising:
a processor of a computing device; and
memory configured to communicate with the processor, the memory having instructions stored thereon that, in response to execution by the processor, cause the computing device to perform operations comprising:
detecting a radio frequency (RF) signal;
determining that the RF signal is generated from an unmanned aerial vehicle (UAV) based on the detected RF signal;
obtaining a color spectrogram image of the detected RF signal;
classifying at least a make and model of the UAV based on the color spectrogram image of the detected RF signal;
sensing for a remote identification field data broadcasted by the UAV;
receiving remote identification information of the UAV from a network database if the network database is available;
assessing a threat likelihood of the UAV based on joint processing of at least the color spectrogram image-based classification of the UAV and the received remote identification information of the UAV; and
signaling an alert containing a description of the UAV and the threat if the UAV if the UAV is assessed as a harmful threat.
