  In [1,2] a new class of intelligent controllers that can semantically embed
an agent in a spatial context constraining its behavior in a goal-oriented
manner was suggested. A controller of such a class can guide an agent in a
stationary unknown environment to a fixed target zone along an obstacle-free
trajectory. Here, an extension is suggested that would enable the interception
of an intelligent target that is maneuvering to evade capture amidst stationary
clutter (i.e. the target zone is moving). This is achieved by forcing the
differential properties of the potential field used to induce the control
action to satisfy the wave equation. Background of the problem, theoretical
developments, as well as, proofs of the ability of the modified control to
intercept the target along an obstacle-free trajectory are supplied. Simulation
results are also provided.
