TDOA/FDOA METHOD AND APPARATUS FOR POSITIONING USING COMBINATION OF TDOA/FDOA

摘要

A method for detecting a location using the combination of TDOA/FDOA is disclosed. The method for detecting a location using the combination of TDOA/FDOA according to the present invention includes: an initialization step of storing location information of a receiver and generating prior information for determining a location or direction of a shadow area; a signal collecting step of collecting pulse signals of a target to measure specification information; and detecting the location of the target by combining information of time difference of arrival (TDOA) and frequency difference of arrival (FDOA). Accordingly, the present invention can prevent the degradation of location detection performance.
