Abstract-The fundamental performances of a radio source localization system were evaluated using the spatial information of the received signals by array antenna in outdoor experiments. We used the angle-of-arrival-based and newly proposed methods to estimate the location of a terminal. The proposed method of localization is based on the fingerprinting technique and uses the signal subspaces of the received signal by using an array antenna as the feature quantity. We confirmed that the proposed method successfully estimates the location of a terminal through the outdoor experiments, whereas conventional methods, such as angle-of-arrival-based method, fail to accurately estimate the locations of sources under non line-of-sight conditions.
The work presented in REF showed however that angle of arrival techniques can also be used in non-line-of-sight conditions when combined with fingerprinting techniques.
