Abstract: eSAT pushes 3D scene awareness and targeting to forward positioned mobile operators and their handheld devices in environments such as found in military theaters of operation, border control and enforcement, police operations, search & rescue and large commercial industrial operations. A host computer hosts a 3D model of a scene and dynamically captures and transmits a windowed portion of the visual representation of that 3D model over a wireless network to the mobile operators' handheld devices. The windowed portion of the visual representation is streamed directly to the operators' handheld device displays. The mobile operators may interact with and control the 3D model via the wireless network. The host computer may synthesize the visual representation of the 3D model with live feeds from one or more of the handheld devices or other assets to improve situational awareness.

Abstract: An infrared imaging system uses an uncooled elliptical surface section between reflective surfaces to allow a detector to perceive a cold interior of a vacuum chamber rather than a warmer surface of a structure or housing. In this way, background infrared radiation from within the system may be minimized.

Abstract: The present invention provides a missile seeker simulator (10) including a means for supplying a hot, point-like target against a given temperature background. The missile seeker simulator (10) includes a background source consisting of a hot cavity blackbody (56), fiber optic cable (64), silicon wafer (68), and controllable temperature source (76). The hot cavity blackbody target source (56) generates infrared radiation (58) in a wide bandpass. The fiber optic cable (64) receives and transmits the radiation (58) from the hot cavity blackbody (56). The silicon wafer (68) is remotely located from the hot cavity blackbody (56) and is positioned such that a pinhole (72) in the silicon wafer (68) is proximate a radiation emitting end (74) of the fiber optic cable (64). The silicon wafer (68) is also positioned in radiation receiving relation to the controllable temperature source (76).
