TARGET INFORMATION PROCESSOR

PURPOSE:To improve the target accuracy and to use a filtering device efficiently by synthesizing target information concerning one target to be assigned to one filtering device when the detection data number is larger than a fixed value. CONSTITUTION:A assignment number judging device 25 with a single parameter indicates the filtering device 20 assignment number by 1 to a management device 27 when detection data number more than a fixed value is input from a radar signal processor during a fixed time from the detection data number obtained by test and tracking input from a target information calculating device 23 and a current time input from a time generating device 24. If the detection data obtained by tracking is not the only one to a target, a target information integrating device 26 integrates plural target information concerning the same target. The management device 27 gives an instruction to one filtering device 29 to process target information calculated on the basis of one detection data obtained by test and the integrated 26 target information with data calculated by the target integrating device 28 such as estimated position and speed and so on.
