Optical sensor algorithms in the JANUS(T) ground combat simulation do not include a repeated detection criterion for target acquisition and weapon firing, nor do they provide for the effects of false detections. As a result, targets detected with very low probability, such as those at ranges near the performance limit of the sensor, will often give rise to acquisition and weapon-firing decisions when rare single detections result from coverage by many sensors and time cycles. This Note reviews the detection algorithms for optical sensors implemented in JANUS(T), identifies some approximations that can lead to overoptimistic estimates of target acquisition probabilities when the calculated detection probability is small, and suggests an acquisition criterion that alleviates the problem.
