PROBLEM TO BE SOLVED: To solve a problem of conventional technology by providing a tsunami detector using an ocean radar capable of detecting tsunami on the basis of a flow calculated by removing a background flow from an observation flow directly observed by the ocean radar, a tsunami detection program using the ocean radar, and a performance verification method for the ocean radar.SOLUTION: The tsunami detector using the ocean radar includes observation flow fluctuation calculation means, reference flow rate calculation means, background flow fluctuation calculation means, moving flow fluctuation calculation means, notice point fluctuation extraction means, comparison point fluctuation extraction means, correlation degree calculation means, and tsunami determination means. The correlation calculation means obtains a correlation degree between a notice point fluctuation and a comparison point fluctuation. Tsunami determination means determines occurrence of tsunami when the correlation degree exceeds a predetermined correlation threshold.SELECTED DRAWING: Figure 4
