The present invention relates to systems and methods that allow one or more users to actively and interactively play games. The invention combines active game play with virtual reality game play to provide a new and improved experience to players. Players can compete against each other by using a variety of targets and computerized scoring. The invention can track when an object or target is struck or comes in proximity of another object or target. Advantageously, the invention can be used by players of a wide range of ages, skill levels, and physical abilities.

The invention relates to a portable electronic signal generator, and in particular a programmable multi-waveform radiofrequency generator for use as battlefield decoy.

A portable sensor calibration target includes a frame assembly, a first panel, and a second panel. The frame assembly may include three legs and a plurality of frame edges that is configured to form a first frame and a second frame and is configured to be held at a pre-selected height above ground by the legs. The first panel is removably attached to the first frame in an unfolded position, and includes a plurality of boards and a plurality of hinges connecting the plurality of boards. The first panel is configured to fold at the plurality of hinges into a folded position. The second panel is removably attached to the second frame adjacent to the first frame. The first panel and the second panel meet to form an edge, which is detectable by a detection system of a vehicle for calibrating the detection system.

Target shooting systems and methods are disclosed herein for exposing shooters to simulated muzzle flashes and monitoring training using a computing device, software application, audio, video, an electrocardiogram (EKG), and wireless communications. The target shooting replicates the visual and audio experience of a muzzle flash thereby simulating live return fire as closely as possible while maintaining safety. The trainee has the ability to shoot live ammunition at a target that is simulating shooting back at the trainee. The EKG is able to measure heart rates over time and transfer the data to the software application on the computing device. The video camera can transfer recorded video data to the software application. Sensors on the target can transfer impact data to the software application so that hit/miss ratios can be calculated. Target systems can include metal targets or cardboard targets.

Embodiments of the present invention relate to a chaff electronic countermeasure device. The device comprises an antenna that is in communication with a substrate. An integrated circuit is in electrical communication with the conductive antenna element. The conductive antenna element includes a conductive composition. The conductive composition includes a conductive polymer and graphene sheets. The device is configured to absorb from a radar source a first radio frequency having a first amplitude. The device is configured to absorb from a radar source a first radio frequency having a first amplitude. In response to absorbing the first radio frequency, the device is configured to reradiate at least a portion of a second radio frequency having a second amplitude toward the radar source, which results in an increased radar cross section of the device as perceived by the radar source. The second amplitude is higher than the first amplitude.

An aerial drone or unmanned aerial vehicle (UAV) is provided for radar calibration testing. The drone includes an airframe including a fuselage with nose and tail, wings and elevators. The drone includes at least one antenna attached to the airframe, as well as a signal adapter coupled to the antenna to receive impinging radar signals and transmit an electromagnetic (EM) field that effectively cancels or combines with the scattered field of the drone, depending upon the adapter's mode of operation. In the first mode of operation, the adapter transmits an EM field that has an opposite phase to the drone's scattered field thereby reducing the radar cross-section of the drone. In the second mode, the adapter transmits an EM field that is in-phase with the scattered field thereby increasing the radar cross-section of the drone.
