Magnetic/Electromagnetic Sensor Array for Detection and Characterization of Underground Facilities

Visidyne proposes to develop a high-fidelity, real-time Nuclear Optical Dynamic Digital Image Generator (NODDIG) to support the development and testing of algorithms for the mitigation of optical clutter in nuclear environments. The NODDIG concept is asoftware/hardware digital scene generator. It would complement and support display systems employed in hardware-in-the-loop sensor testing, such as the analogue infrared simulator in DTRA's Nuclear Optical Dynamic Display System (NODDS). Presentlyavailable image generators are either too slow or afford incomplete models of the burst-disturbed backgrounds from high-altitude nuclear events (HANEs). The IRSim code, developed and maintained by Visidyne, is the DTRA standard for producing high-fidelitystructured scenes and scene sequences. However, IRSim is several orders of magnitude too slow to be used in
