Baseline Test of a Matched Filter Correlator for Screening Aerial Reconnaissance Film,
Abstract
An optical matched filter image correlator previously reported upon was used to perform a screening mission on aerial reconnaissance film with limited sampling of various terrain imagery. The sampling was limited to several scans of each image in the correlator plane. The target was generally recognizable when the signal-to-clutter ratio was in the range of one to ten dB depending upon the type of terrain and the band pass characteristics (or order) of the matched filter used. In some cases false alarm detection was experienced and a tradeoff between false alarms or clutter, and probability of detection can be made. The results obtained through the sampling of the correlation plane show that the probability of detection could be 99 percent for the most complex terrain encountered if 10.5 percent false alarm rate are also accepted. Thus, the correlator can perform the screening mission. Predictions on the system detection of targets in various terrain are given. (Author)
