Wave height calculation device, radar device, and wave height calculation method

摘要

An object of the present invention is to accurately calculate a wave height regardless of the wave traveling direction in which the wave height is calculated. A wave spectrum power calculation unit for calculating a wave spectrum power √m ₀ in an analysis area included in a detection area and a wave in the analysis area based on a direction from the analysis area toward the receiver. A wave spectrum power correction unit 17 that corrects the wave spectrum power √m ₀ based on the relative wave direction θ that is the traveling direction, and a wave height of the wave in the analysis area based on the corrected wave spectrum power √m _{0_new.} A wave height calculation device 10 including a wave height calculation unit 18 that calculates H _1/3 is configured.
