<p>PROBLEM TO BE SOLVED: To reduce erroneous judgement of correlative processing and minimize lowering of radar resolution with regard to search tracking by estimating target observation precision at a real time, and successively determining correlative gate width used at the time when correlative processing of a caught target and a tracking target is performed on the basis of the estimation value. SOLUTION: A radar signal processor 3 calculates the three-dimensional observation value of a target from S/N out of receiving signals, and output it to an observation value output selection device 4 and an observation precision estimation device 6. The device 6 calculates the estimation value of observation precision of an angular direction on the basis of S/N at the time of detecting the target, and output it to an observation precision correlative gate width setting device 10. The device 10 calculates correlative gate width from probability observed in a correlative gate. A correlative device 16 performs correlative processing between a tracking prediction position and the observation value of a search target, judges whether the search target is new one or not, if it is the new target, irradiation information is transmitted to a beam controller 17, and the command of tracking and irradiation of a search beam is output to a transmitting and receiving device 2.</p> |
