Abstract : CONNAISSANCE PHOTOGRAPHS. A narrow-band transmission link employing the REARCS technique was simulated by computer program. The program demonstrated the effects of digital link anomalies on REARCS-coded photographic data. Actual sampled picture data is used as an input with reconstructed picture data, showing coding and link effects, as the output. Important factors in transmitting photographs are scanning and digitizing the original photo for transmission and reproducing it on the receiving end of the link. The interrelationships between optical, electrical, and mechanical parameters of photo scanning/reproducing equipment affects the quality of the received pictures. A Scanner/Reproducer Simulation software program was developed to assist in selecting appropriate parameters for future hardware systems. (Author)
