Abstract: Systems, methods, and computer-readable media are described for compact radar systems. In some examples, a compact radar system can include a first set of transmit antennas, a second set of receive antennas, one or more processors, and at least one computer-readable storage medium storing computer-executable instructions which, when executed by the one or more processors, cause the radar system to coordinate digital beam steering of the first set of transmit antennas and the second set of receive antennas, and coordinate digital beam forming with one or more of the second set of receive antennas to detect one or more objects within a distance of the radar system.

Abstract: A flying vehicle is disclosed with a projectile module or component that contains a projectile for projecting at another flying device. The flying vehicle receives an identification of a target flying device and applies a projectile model which generates a determination that indicates whether a projectile, if fired from the projectile component, the projectile will hit the target flying device. The projectile model taking into account one or more of a wind modeling in an area around the flying vehicle based on an inference of wind due to a tilt of the flying vehicle, a projected path of the target device based on its identification and a drag on the projectile as it deploys from the projectile component. When the determination indicates that the projectile will hit the targeted device according to a threshold value, the flying vehicle fires the projectile at the targeted flying device.

Abstract: An example method can include receiving, at a sensor, a signal associated with a motion of a target, processing the signal via a first filter having a first motion model and a second filter having a second motion model to yield a first tracking output and a second tracking output for the target, and weighting the first tracking output and second tracking output according to how well each of the first motion model and second motion model represents the motion of the target, to yield a first weight for the first tracking output and a second weight for the second tracking output. The method can include combining the first tracking output and second tracking output to yield a fused tracking output and sending, to a fusion system, the fused tracking output, the first weight associated with the first tracking output and the second weight associated with the second tracking output.

Abstract: Systems, methods, and computer-readable media are described using radar systems to avoid vehicle collisions. An example radar system can include antennas mounted on an aircraft, where each antenna has a different orientation facing a different direction away from the aircraft. The radar system can include one or more processing devices and a computer-readable storage medium storing instructions which, when executed by the one or more processing devices, cause the radar system to coordinate digital beam steering and digital beam forming with the antennas to produce a radar coverage area that includes a portion of an airspace around the aircraft; detect, based a signal transmitted by the antennas using the digital beam steering and digital beam forming, an object within the radar coverage area; and generate collision avoidance information including an indication of the object detected within the radar coverage area and/or an instruction for avoiding a collision with the object.

Abstract: A system having an array of antennas with particular weights for signals associated with different groups of antennas. The array of antennas includes a first group of antennas positioned in a middle portion of the array of antennas, a second group of antennas positions at one or more edges of the array of antennas, and a third group of antennas positioned at one or more corners of the array of antennas. The system includes a control module configured to control each respective and tenant in the array of antennas. The control module can further be configured to weight the first group of antennas a first weighting amount, to weight the second group of antennas a second weighting amount and to weight the third group of antennas a third weighting amount. The weighting improves the system's ability to reduce ambiguities in an angle of arrival associated with the object.

Abstract: A projectile module is attached to a gun component which operates as a system to launch a projectile at a flying device. The gun component is configured to be removably and electro-mechanically attached to a flying vehicle. A cylindrical gas valve is part of the gun component and has a safety component configured on an exterior surface of the cylindrical gas valve to enable the gun component only to attach to the flying vehicle when the projectile module is locked into position. A splitter component configured on the gun component adjacent to the cylindrical gas valve and has an output opening for gas flow. The projectile module is removable and includes weights attached to a projectile, wherein the weights are positioned in channels on the projectile module. The projectile is fired when gas flow is initiated from a reservoir the cylindrical gas valve and splitter component to the channels containing the weights.
