A method for interpolated virtual aperture array radar tracking includes: transmitting first and second probe signals; receiving a first reflected probe signal at a radar array; receiving a second reflected probe signal at the radar array; calculating a target range from at least one of the first and second reflected probe signals; corresponding signal instances of the first reflected probe signal to physical receiver elements of the radar array; corresponding signal instances of the second reflected probe signal to virtual elements of the radar array; interpolating signal instances; calculating a first target angle; and calculating a position of the tracking target relative to the radar array from the target range and first target angle.

Methods and apparatus for determining an angle of arrival in a radar warning system that uses tracking to provide a more accurate angle of arrival than conventional systems. In exemplary embodiments, angle of arrival and range are mapped from measured body angles to a 3D coordinate system where modern tracking techniques are applied to improve accuracy and stabilization of measurements, then mapped back into body angles for display.

A system for providing integrated detection and deterrence against an unmanned vehicle including but not limited to aerial technology unmanned systems using a detection element, a tracking element, an identification element and an interdiction or deterrent element. Elements contain sensors that observe real time quantifiable data regarding the object of interest to create an assessment of risk or threat to a protected area of interest. This assessment may be based e.g., on data mining of internal and external data sources. The deterrent element selects from a variable menu of possible deterrent actions. Though designed for autonomous action, a Human in the Loop may override the automated system solutions.

A gimbal-assisted continuous-wave (CW) Doppler radar detection system mountable to an unmanned aircraft system may be rotated in three degrees of freedom relative to the UAS to provide targeted multidirectional obstacle detection by transmitting CW signals throughout a field of view and analyzing reflected signals from obstacles within the field of view. The radar assembly may be articulated to provide track-ahead detection in anticipation of a heading or altitude change of the UAS, to center on a detected obstacle in order to classify or identify it more clearly. The radar assembly may be rotated below the UAS and its field of view changed to increase breadth and accuracy at a shorter effective range, in order to determine real-time altitude or terrain data while the UAS executes a landing.

A system for improving a basketball player's ability to shoot basketballs towards a basketball hoop having an improved ball sensor is disclosed. An interface allows a player to select various locations for a ball ejector to launch basketballs to. A hollow protrusion extends though the net of the basketball hoop and has a microphone positioned therein. A processor compares audio signals generated by said microphone to pre-recorded sample audio signals of a basketball passing through the net of the basketball hoop to determine if a basketball shot was successfully made.

An electronic device detects an object reflecting transmitted waves based on transmitted signals transmitted as the transmitted waves from transmitting antennas and received signals received from receiving antennas as reflected waves obtained by reflection of the transmitted waves. The electronic device determines that the object have been detected when the peak in the result obtained by performing a Fourier transform process on the beat signals generated based on the transmitted and received signals is equal to or higher than a predetermined threshold value. The electronic device sets a predetermined threshold value based on an object detection probability.
