- Many of the standard considerations for modeling of target acquisition of stationary targets in a single field of view must be altered when considering target acquisition in the actual battlefield. Sensors are scanning, targets are moving, and the detection process is considerably more complex than the analysis of the highest detectable frequency detectable superimposed on the target size. In this paper, we discuss several of the issues involved. The use of a single detectable frequency to model the target acquisition process is not sufficient. We consider the replacement of this model with one consisting of an integral of the target spectrum, taking into account the spatial frequency MTF dependence of the imaging system.
