A measure of performance of battle information systems, called information gain, has been under development by faculty and cadets at the US Military Academy. It is based on decreases and increases in Shannons entropy that result from receipt of data by a tactical commander. Such data might include, for example, reconnaissance reports, movements of the opposing forces and results of engagements. We have investigated the effects of target mobility on information loss when surveillance of a target is broken. This is based on a simple stochastic model of target movements, together with an approximation appropriate for implementation in a spreadsheet. We found the shapes of information loss curves are dependent on terrain features affecting the movement of the target, and that information is lost surprisingly rapidly once contact with the target is lost.
