N2  - A lensless pinhole camera is mounted on a rotating frame, and a sensor fixed relative to this frame receives the location of a point P maneuvering in 3. Using these measurements, the angular velocity vector w of the rotating frame is chosen in such a manner that the camera can track the motion of P. The point P receives its location relative to an inertial (fixed in space) coordinate system, and using these measurements, it wishes to choose its control functions [nu]1 and [nu]2 in such a manner as to avoid being tracked by the camera. First, an auxiliary stochastic optimal control problem is solved, and then, a suboptimal guidance law ([nu]10, [nu]20) is obtained.<p />
