Abstract
In this study, an analog circuit for target tracking system was proposed and designed by using analog circuit for motion detection based on the biological vision system. Analog circuit for detecting sound localization was also proposed based on the biological auditory system previous proposed. The proposed circuits were evaluated by the simulation program with integrated circuit emphasis (SPICE). The simulation results showed that the circuit based on the vision system can output the signal for target tracking and the circuit based on auditory system can output the signal for detecting sound localization.
