PROBLEM TO BE SOLVED: To provide a hazardous target detection device capable of detecting plural categories of hazardous targets.SOLUTION: A hazardous target detection device 3 includes an echo detection part 8 and a hazardous target detection part 10. The echo detection part 8 uses an echo signal to detect a target. The hazardous target detection part 10 uses the detection result of the echo detection part 8 to detect whether the target is a hazardous target, and is configured to detect existence of a hazardous target at every predetermined unit period of time so as to be capable of detecting a projecting target, as a hazardous target, the target that does not exist at the (n-1)-th scan and appears at the n-th scan. |
