<p>PURPOSE:To conduct a uniting processing even for tracks acquired by sensors of which the timings of sampling are different. CONSTITUTION:Sensors 2-1 to 2-n acquire a target at the respective timings of sampling. Based on information on the target acquired thereby, filters 3-1 to 3-n prepare tracks. A time difference detecting device 4 detects differences between the time when the sensor (n) denoted by 2-n detects the target and the times when the sensors 2-1 to 2-n-1 detect the target. Using these time differences and the tracks from the filters 3-1 to 3-n-1, preestimating devices 5-1 to 5-n-1 preestimate the track at the sampling timing of the sensor (n). The preestimated track and the track obtained from a filter 3-n are subjected to a uniting processing by a uniting device 6.</p> |
