Title:
LOCALIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/162669
Kind Code:
A1
Abstract:
In this localization device, a determination processing unit (5) is provided which uses a TDOA11,i and TDOA22,j calculated by an autocorrelation processing unit (4) to determine whether or not a TDOA12,k, calculated by a cross-correlation processing unit (3), is the time difference of arrival resulting from direct waves emitted from a radio source. A localization processing unit (6) localizes the radio source by using the TDOA12,k calculated by the cross-correlation processing unit (3) that the determination processing unit (5) has determined to be the time difference or arrival resulting from the direct waves.
