Abstract :
Smart sensor arrays make use of integrated motion detection circuits for target tracking. Tracking a velocity varying target is a difficult task that usually leads to a complex design and implementation. We propose an approach to target tracking that uses foveated sensor arrays that can lead to a simple design and implementation. An example system of the proposed approach is modeled and simulated. Results show improved tracking over a uniform sensor approach.
