DEMONSTRATION OF FEASIBILITY OF AIR-TO-GROUND PHOTO TRANSMISSION IN NEAR-REAL TIME.
Abstract
This report is the result of a test which demonstrated the feasibility of photo transmission in near-real time. Pre-processed, high-resolution photographic reconnaissance imagery was transmitted from an aircraft to a ground station where it was recorded, processed, and ready for viewing within 22 seconds. The aircraft flew at six different altitudes (from 750 to 40,000 feet) and at day, dusk, and night. Two thousand feet of film from 32 flight passes (ground-station to line-of-sight) were evaluated. Imagery was received at ranges out to 90 to 100% of geometric line-of-sight, depending upon aircraft altitude. Photo interpretation and photogrammetric analysis and evaluation were conducted on original and transmitted imagery. The principal finding of the phot interpretation study was that altitude, range, and time of day (within the conditions studied) do not degrade the accuracy and completeness with which an interpreter reports the target-content of the transmitted imagery. The photogrammetric analysis and evaluation showed that the scanning and recording equipments were essentially the only contributors to the loss in quality of transmitted imagery. (Author)
