Abstract:
A system for detecting, classifying and tracking unmanned aerial vehicles (UAVs) comprising: at least one microphone array arranged to provide audio data; at least one camera arranged to provide video data; and at least one processor arranged to generate a spatial detection probability map comprising a set of spatial cells. The processor assigns a probability score to each cell as a function of: an audio analysis score generated by comparing audio data to a library of audio signatures; an audio intensity score generated by evaluating a power of at least a portion of a spectrum of the audio data; and a video analysis score generated by using an image processing algorithm to analyse the video data. The system is arranged to indicate that a UAV has been detected in one or more spatial cells if the associated probability score exceeds a predetermined detection threshold.

Claim (Index 1):
A system for detecting, classifying and tracking unmanned aerial vehicles in a zone of interest, the system comprising:\n at least one microphone array including a plurality of microphones, the at least one microphone array being arranged to provide audio data; at least one camera arranged to provide video data; and at least one processor arranged to process the audio data and the video data to generate a spatial detection probability map comprising a set of spatial cells, wherein the processor assigns a probability score to each cell within the set of spatial cells, said probability score being a function of: an audio analysis score generated by an audio analysis algorithm, said audio analysis algorithm comprising comparing the audio data corresponding to the spatial cell to a library of audio signatures; an audio intensity score generated by evaluating an amplitude of at least a portion of a spectrum of the audio data corresponding to the spatial cell; and a video analysis score generated by using an image processing algorithm to analyse the video data corresponding to the spatial cell, wherein the system is arranged to indicate that an unmanned aerial vehicle has been detected in one or more spatial cells within the zone of interest if the probability score assigned to said one or more spatial cells exceeds a predetermined detection threshold.
