PROBLEM TO BE SOLVED: To eliminate the danger of malfunction even without stopping the operation of a radar system at the time of passing through a gate by arranging left and right partition walls for determining a passage so as to make the positions of front ends longitudinally different. SOLUTION: The gate is composed of partition walls P, Q and R partitioning plural passages and the ceiling supported by these partition walls (A). Among three adjacently arranged partition walls P, Q and R, the central partition wall Q is arranged at the back of both the adjacent partition walls P and R (B). The front ends of the partition walls P and Q detected by a radar loaded vehicle V to pass through the passage on the left side of this gate are longitudinally discrete like reflecting points (p) and (q) (C). As a result, even when the detected reflecting points are grouped in this radar system, since these reflecting points (p) and (q) are longitudinally sufficiently discrete, the presence of one continuation such as large vehicle or building including these reflecting points is not erroneously detected.
