Evaluation of target recognition in aerial reconnaissance film using optical matched filter processing

An optical matched filter image correlator (OMFIC) was used to assess the probability of detection of an M-60 tank in a variety of terrains. A tradeoff between false alarms or clutter and the probability of detection can be made for each terrain type. Results show that as the number of target aspect factors decrease, the probability of detection increases rapidly. It is concluded that the OMFIC system demonstrates acceptable target discrimination for screening aerial reconnaissance films.
