Abstract: The present invention is for a system and method for testing an RF/radar system in a simulated open-air environment. During a test, the RF/radar system-under-test interfaces directly with the simulated open-air environment and operates in real time. For test purposes, an environmental database is provided to mimic the simulated open-air environment using a plurality of digitized impulse functions. A computation engine then cross-correlates the digitized impulse functions of the environmental database in fast time with digitized RF transmissions from the system-under-test to format a digital convolution. The digital convolution is then test-evaluated. For the present invention, the digital convolution is based on the theory of Green's Functions and is influenced by propagation and reflection physics (i.e. Maxwell's Equations) that are pertinent to the simulated open-air environment.

Abstract: A simulator is provided for dynamically testing and evaluating an electromagnetic radiation in real-time. The performance of radiation from a system-under-test is evaluated as it interacts with a moving target in an ever-changing simulated environment. The simulator includes a computer for synchronized control of a PNT database and of an environmental database. In detail, the PNT database contains Position, Navigation and Timing (PNT) information of the target, and the environmental database contains information pertaining to meteorological conditions and topographical characteristics in the simulated environment. In combination, the computer evaluates a synchronized interaction of the electromagnetic radiation with the PNT information from the PNT database, under conditions set by the environmental database. A response record for evaluating a performance of the system-under-test is thereby created.

Abstract: A system for visually tracking the trajectory of an in-flight golf ball through an x-y-z space above a driving range includes a plurality of cameras for respectively creating a video stream of the x-y-z space. Each video stream is presented on a dedicated camera focal plane with information on respective azimuth angles ? and elevation angles ? from the particular camera to the in-flight golf ball. A central computer is connected with the camera focal plane of each camera to identify a start point for the golf ball, to track its trajectory in the x-y-z space, and to filter out background clutter. A visual display is provided to show the in-flight golf ball from its start point to a target point in real time.

Abstract: A radar antenna system includes a single transmitter for creating pulses from a wideband waveform. A splitter divides each pulse into half-power pulses, and sends them along respective paths. On one path, successive half-power pulses are alternately modulated with a phase shift ?A or ?F. On the other path, the half-power pulses are not modulated. Each modulated half-power pulse is then combined with an un-modulated half-power pulse to transmit pulses of a full aperture beam with either ?A or ?F. This establishes two degrees of freedom for the system. Two separate receivers then simultaneously receive the pulse echoes and a signal processor uses the consequent four degrees of freedom to create a radar indicator with mitigated clutter and useable azimuth estimation. A coherent processing interval can then be selected for multi-mode operation of the system.

Abstract: A system and method for including an entertainment aspect in an individual's training/practice session for throwing/kicking/hitting (i.e. launching) a ball, requires recording a video stream(s) that includes images of the individual's body motions and the resultant flight trajectory of the ball. Images from the video stream(s) can then be used, with appropriate metrics, to study the motion kinetics of the individual and the ball's resultant flight trajectory, to evaluate the individual's performance in launching the ball. Also, images from the video stream can be edited by the individual for subsequent training or entertainment purposes.
