An indication of a detected security event is received. One or more sensors are selected based on the detected security event. The selected sensors are used to detect additional information associated with a protected airspace associated with the detected security event. A risk level assessment associated with the detected security event is determined based at least in part on the additional information detected using the selected sensors. A response is automatically invoked based on the determined risk level assessment.
An aerial vehicle system is comprised of a detector, a signal generator, and a transmitter. The detector is configured to detect a presence of a target unmanned aerial vehicle within a range of the aerial vehicle system. The signal generator is configured to generate a communication disruption signal. The transmitter is configured to trigger a transmission of the communication disruption signal based in part on the detected presence of the target unmanned aerial vehicle.
An aerial vehicle system comprises a radar system and a processor. The radar system is configured to transmit a radar signal. The transmitted radar signal is reflected off an object to produce a reflected radar signal. The radar system is configured to receive the reflected radar signal and provide a signature associated with the reflected radar signal. The signature has been adjusted based at least in part on a flight parameter of the aerial vehicle system. The processor is configured to classify the object as an unmanned aerial vehicle based on the adjusted signature and initiate an action based on a classification of the object.

Example implementations associated with the aspects of the present invention include a low altitude aircraft identification system composed by three components: a small aircraft electronic identification box with an embedded logger, a ground identification equipment to automatically identify the aircraft just pointing at it, and an identification code database. The identification code can be transmitted by a visible light color sequence or by a radio frequency signal. The ground identification device is capable of recognizing both kinds of code.
A wireless communication receiver is used to receive a wireless signal that identifies an identifier transmitted by an aircraft. A token value and a vehicle identifier are obtained from the received transmitted identifier. A secret corresponding to the vehicle identifier is obtained. A synchronized time value is obtained. A comparison token value is generated using the secret and the synchronized time value. The obtained token value and the generated comparison token value are compared to determine an authenticity of the received transmitted identifier.

A flight control operation of a reference aerial vehicle is performed. For example, an image captured by an image sensor of the reference aerial vehicle is received. A target is detected in the image. A three-dimensional relative location of the target with respect to the reference aerial vehicle is determined based on the image. The flight control operation is performed based on the three-dimensional relative location of the target with respect to the reference aerial vehicle.
A system and method for identifying an unmanned aerial vehicle (UAS) detected in a location is provided. The system may include a reader having a receiver configured to receive identification information, and a transmitter configured to re-transmit the received identification information; and an identification server having a memory storing UAS registration information, a receiver configured to receive transmissions, a transmitter to transmit information and a processor configured to provide a verification of the identification information received by the reader based on the re-transmitted identification information and the stored UAS registration.

An aerial system discrimination system includes an aerial system disruption system, an aerial system identification system, and a permissions module. The discrimination system can additionally include or use an identifier transmission system configured to mount to the aerial system. The discrimination system functions to determine whether an aerial system is authorized or unauthorized to be in the airspace. The discrimination system can additionally function to prevent, disrupt, remove, or otherwise interact with an unauthorized aerial system within the airspace.

Spatio-temporal awareness engine for priority tree based region selection across multiple input cameras and multimodal sensor empowered awareness engine for target recovery and object path prediction
A spatio-temporal awareness engine combines a low-resolution tracking process and high resolution tracking process to employ an array of imaging sensors to track an object within the visual field. The system utilizes a low-resolution conversion through noise filtering and feature consolidation to load-balance the more computationally-intensive aspects of object tracking, allowing for a more robust system, while utilizing less computer resources. A process for target recovery and object path prediction in a robotic drone may include tracking targets using a combination of visual and acoustic multimodal sensors, operating a camera as a main tracking sensor of the multimodal sensors and feeding output of the camera to a spatiotemoral engine, complementing the main tracking sensor with non-visual, fast secondary sensors to assign rough directionality to a target tracking signal, and applying the rough directionality to prioritize visual scanning by the main tracking sensor.
