Abstract
A system and method for locating objects and/or receiving data associated with an object. An antenna or similar device that can intercept or modify RF energy is caused to vary its properties in accordance with a predefined time sequence pattern that is associated with the object. The antenna device is located proximate to the object to be located. To locate the object, a wide band radar device is utilized to transmit a probe signal and receive and analyze the return signal to identify the predefined pattern and determine the range to the antenna and thus determine the range to the associated object. The time sequence pattern is optionally modulated by a data stream to convey data associated with the object.
