Abstract : An Electronic Optical Scorer (EOS) was developed for installation in USAF MC-5, a rotating training target. The system is a dual-channel passive system designed to detect the obscuration of sunlit background caused by near passage of a missile and to broadcast an FM signal immediately and automatically if the miss-distance is less than 15 ft. The signal is presented by an FM receiver at the monitoring station as a varying frequency tone; no data-processing equipment is required. Four units were fabricated. Ground tests in a stationary target demonstrated the scorer's ability to properly indicate the missdistances. In a flight test in a MC-5 target, a continuous hit signal was transmitted. The spurious signal was attributed to scanning of the horizon line by the multilobed detection patterns as the target rotated. The EOS as designed was accepted for trial in the TDU-9/B, a nonrotating target. (Author)
