Abstract: The present invention provides methods for an active RFID tag target location system that provides for an iterative recalculating of a target location estimate by successively testing receiver TOA and DTOA error measurements and discarding outlier receivers. The present invention works to reduce the erratic effects that multipath channel interference and random noise play in target location systems due to incorrect identification of the main pulse of the transmit signal.

The method may be considered a post-processing element, as the determination of TOA and DTOA may require a real-time calculation, where the timing constraints for the ensuing target location estimate may be less severe.

Abstract: In order to improve the compliance of proper radiography surveys, and to overcome the myriad of human factor and other reasons that may cause an operator—consciously or unconsciously—to not make a survey, the system described herein may serve to transform the survey process from a totally active effort to a largely passive one. The system described herein is active, thus allowing the operator to be more passive in connection with performance of radiation surveys. In concept, according to the system described herein, surveying radiographic equipment and general areas is transformed from the requirement to attentively move an instrument through space while observing a meter panel. Instead, the system described herein enables a process whereby the operator may perform other (non-survey) activities while the survey occurs automatically and provides the results directly to the operator without requiring the operator to make independent, active efforts.
