PURPOSE:To eliminate the need for a skilled operator and to shorten an identification time by deciding whether or not an urgent countermeasure should be taken or not by using various target elements traced by a tracing radar device, and displaying the decision result. CONSTITUTION:A radar effective reflection area calculating part 7 calculates target radar effective reflection area 8 from a specific expression by using an AGC voltage 5 and target range 6, and supplies the area to a target discrimination part 9. The discrimination part 9 decides whether or not a target being traced needs to be dealt with urgently by using a target speed 10, a target course angle 11, and a target azimuth 12 applied from the tracing radar device 4 through an input circuit 3 in addition to the reflection area 8. When it is decided that the target needs to be dealt with urgently, an urgent countermeasure request 13 is outputted on a display device 14 through an output circuit 15. Consequently, a special skilled operator regarding target identification is not necessary and the target is identified simultaneously while the tracing radar begins to trace the target.
