<p>PURPOSE:To prevent such a trouble as the scattering or the abandonment of a target by performing a fetch processing on a signal into a range bin which becomes active without fail when a signal responsive to a transponder moves to an adjacent range bin. CONSTITUTION:The range bin information of a range (n+1) is read from a range bin memory 6 for a range (n) in being swept. When one range bin becomes active, a hit signal present in the other range bin adjacent to the former range bin is fetched into the range bin which becomes active by compar ing the read data of the range (n+1) and the data of the range (n) in being swept with each other in a boundary processing circuit 4. When both the range bins become active, by controlling the circuit 4 such that a response signal that hits one range bin is compulsorily inputted in the other range bin, a target is accurately caught and the separation of the target, the shortage of a run length or the like is prevented.</p> |
