| Summary: | In a target merging process in a radar ranging device, determination of continuity is accurately performed and output processing of newly appearing targets is performed rapidly. The current target position (data prior to merging) is calculated (S
1
), and a predicted position is calculated (S
2
). The continuity of targets whose previous position and current position satisfy predetermined conditions (S
3
to S
5
) is determined (S
6
to S
7
). After the data prior to merging is stored in a buffer (S
9
), the merging process is performed. By storing the data prior to merging in the buffer, continuity is determined for each detected target and, therefore, even if the position of a target changes after merging, subsequent determination of continuity can be performed accurately. |
