Abstract

A simple, real-time electric field sensor intended for proximity estimation is proposed. The sensor relies on capacitive induction to provide source strength and distance estimates. Field gradient information was found to be useful for proximity estimation, and is provided by the sensor configuration. A decision law, that processes sensor data to provide the user with clearance information, is proposed.
