PROBLEM TO BE SOLVED: To provide a technique for simultaneously improving detection accuracy for various targets.SOLUTION: A signal processing unit (3, 4) performs a frequency analysis on a beat signal obtained by sending and receiving a continuous wave and estimates an arrival direction of a received wave. Target detection means (5, 6) executes, on the basis of the processing result from the signal processing means, at least extraction processing (51, 61) for extracting target candidates, tracking processing (52, 62) for tracking targets and target candidates, and target recognition processing (53, 63) for recognizing the target candidates as targets. The target detection means individually executes the extraction processing, the tracking processing, and the targeting processing for every type of the target as a detection object, and changes a processing content depending on a feature of the detection object.SELECTED DRAWING: Figure 2
