| 摘要 |
A high-accuracy path detection (26) is realized by performing correlation processing (16) by using a spread code for each of the reception signals of a plurality of antennas constituting an array antenna (10), performing beam forming (18) to the result of the correlation processing, and creating a delay profile from the result of the beam forming(20, 22, 26). D0A information obtained for the beam forming (18) can also be used as an initial value given to a beam former (33) of a reception signal processor (14). |
