Description

In order to distinguish vehicles without wireless units from those with the units, it is necessary to locate the positions of the wireless units in the free flow Electronic Toll Collection system. We has been proposed the positioning method using two direction finders located above the center of the road, one of which estimates horizontal angle and the other estimates vertical angle. In the method, height of the wireless units must be assumed to complete positioning but the assumption causes positioning errors. In this report, we analyze the relation between the assumption errors and the positioning errors. Physical experiments are also carried out in order to estimate DOA errors of direction finders using array antennas and verify the above analysis.
