A method for tracking a target having substantially constrained movement utilizes the steps of determining constrains for movement of the target, obtaining information on movement of the target, and predicting that the target will continue to move upon a route segment after the target has begun to move thereupon. The constraints are made up of a plurality of separate alternate route segments. Predicting that the target will continue to move upon the route segment upon which it is previously moving facilitates targeting, intercept and intelligence with a substantial degree of reliability, particularly when continuing information, such as radar returns, is not available.

[ What is claimed is:] [22.]22. A method for predicting target location and movement for a target restricted to ground travel through an environment containing physical constraints, the method comprising steps of:(a) obtaining a location for each of the respective constraints;(b) acquiring a target position and a target direction of movement by radar detection;(c) determining whether any constraints restrict target movement along the target direction of movement;(d) predicting constrained route segments for the target in response to a determination that target movement along the target direction of movement is restricted by one or more of the constraints, comparing the constrained route segments with a subsequent target position, and classifying the constrained route segments in a low confidence category when the subsequent target position does not correspond with the constrained route segments within a threshold association;(e) predicting unconstrained route segments for the target in response to a determination that target movement along the target direction of movement is not restricted by the constraints.
