Abstract
An array of antennas form a sensor device. Some of the array of antennas function as receivers and some of the array of antennas function as transmitters. Each of the transmitters may transmit a unique frequency orthogonal signal that may be received at the receivers. Measurements of the received signal are then used to determine activity within field lines.
