Patent ID: 7394244

Claim:
A through wall position sensor system comprising: at least one field producing element separated by a wall from an array of sensors, wherein the array of sensors detects a property associated with the at least one field producing element and outputs a corresponding output signal indicative of the property associated with the at least one field producing element; and a processor communicatively coupled to the array of sensors for processing the output signal from one or more sensors, wherein the processor utilizes a tracking curve fit algorithm to analyze the output signal from the one or more sensors by fitting the output signals to a bell-shaped characteristic curve, wherein the tracking curve fit algorithm utilizes an iterative calculation that takes into account one or more prior sensor output signals to determine at least one of a lateral position of and/or a height of the bell-shaped characteristic curve and a best fit of the output signals to the bell-shaped characteristic curve to determine a position associated with the field producing element.
