Abstract
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 ), and a predicted position is calculated (S ). The continuity of targets whose previous position and current position satisfy predetermined conditions (S to S ) is determined (S to S ). After the data prior to merging is stored in a buffer (S ), 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.
