Range Resolution of Targets Using Automatic Detectors.
Abstract
When two targets are closely separated in range, automatic detectors will declare the presence of only one target. To increase the probability of resolving targets in range, log video should be used and the threshold should be of the form T=Mu + F, where the mean Mu is the smaller of the two means calculated from a number of reference cells on either the greater range side of the test cell or the lesser range side and F is a fixed number. When the adjacent-detection merging algorithm (which decides that detections at the same azimuth and elevation in adjacent range-resolution cells are from the same target) is used, the probability of resolving targets does not rise above 0.9 until the targets are separated in range by 2.5 pulse widths.
