Zhu, Zhen Vana, Sudha Bhattacharya, Sumit Uijt de Haag, Maarten Integration of forward-looking infrared ( FLIR) and traffic information for moving obstacle detection with integrity We discuss some of these challenges, how they were met, and the performance of the flight-demonstration system. Unexpected as well as expected challenges were encountered. Other changes included the transition to rugged hardware that would withstand the fighter aircraft environment, and the need for the system to be compact and self-contained. The obvious changes required were in the interfaces: the flight system must get live FLIR imagery from a sensor it must get platform location, sensor data, and controls from the avionics computer in the aircraft via 1553 bus and it must get SAR cues from the on-board SAR system, also via 1553 bus. We discuss the transition from laboratory demonstration to flight demonstration for this system. This ATR system, however, was intended to ultimately be flown in a fighter aircraft. For the laboratory demonstration, FLIR images, platform location, sensor data, and SAR cues were read in from files stored on computer disk. Model-based automatic target recognition (ATR) using forward- looking infrared ( FLIR) imagery, and using FLIR imagery combined with cues from a synthetic aperture radar (SAR) system, has been successfully demonstrated in the laboratory. Transition from lab to flight demo for model-based FLIR ATR and SAR- FLIR fusionĬhilds, Martin B. polar bear, infrared imagery, maternal denning, human impacts, management Data suggested that FLIR surveys conducted during optimal conditions for detection can produce detection rates approaching 90 percent and thus can be an important management and mitigation tool. The estimated probability of detecting dens in sunlight was 0. The odds of detecting a den were 4.8 times greater when airborne moisture (snow, blowing snow, fog, etc.) was absent than when it was present, and they increased 3-fold for every 1?C increase in temperature-dew point spread. Four dens were never detected (17 percent), but three of those were visited only under marginal conditions. Nine dens were always detected, and 10 dens visited more than once were detected on some flights but not on others. To mitigate potential disruption of polar bear denning by existing and proposed petroleum activities, we used forward-looking infrared ( FLIR) viewing to try to detect heat rising from dens.We flew transects over dens of radio-collared females with FLIR imager-equipped aircraft, recorded weather conditions at each observation, and noted whether the den was detected.We surveyed 23 dens on 67 occasions (1 to 7 times each). The survival and development of cubs is dependent on a stable environment within the maternal den. Polar bears give birth in snow dens in midwinter and remain in dens until early spring.
