RADAR RANGE FINDER

摘要

PROBLEM TO BE SOLVED: To obtain a radar range finder which can accurately perform continuous decision and extrapolation processing.

SOLUTION: The processing comprises performing continuity decision and extraporation processing to decide whether position data of a target object is within a detection range of the device prior to data update (S6 and 9); and stopping the continuous decision and extraporation processing in the case where the position data is outside the range. Further, the processing is stopped in the case where the time when the position data is outside the detection range exceeds a predetermined time or where the target object is within a specific region. This can prevent the position data whose accuracy is low and which is outside the detection range from being used as data on the ranging results.
