Simple analog-digital motion detection circuit and its application to target tracking systems

摘要

We propose an analog-digital circuit for detecting the movement of an object. The proposed unit circuit is a simple structure since the digital part of the circuit is constructed with only one NOT circuit and one NOR circuit. The measured results on a constructed test circuit showed that the proposed circuit can output the pulsed voltage (motion signal) when an object moves on the circuit. We proposed and constructed the system in this study in order to track target. Since the array in the proposed circuits was introduced at the first stage of the system, the circuit for tracking the target became a simple structure. It was clear from the measured results of the test system that it can track and capture a target in the center of the input section.
