摘要： PROBLEM TO BE SOLVED: To provide a device for measuring a road-surface roughness distribution wherein the partial rough distribution of a road surface is acquired. SOLUTION: A device for measuring a road-surface roughness distribution is provided with an antenna 13 which emits a measurement wave 11 toward a road-surface 12 and receives a scattering wave which is generated when the measurement wave 11 is reflected on the roughness of the road-surface 12 and scattered, rotating means 20 and 21 which rotate the antenna 13 in the plane orthogonal in the emission direction of the measurement wave 11, a transmitting/receiving means 16 which generates and amplifies the measurement wave while amplifies the received scattered wave, a processing means 22a for processing the scattered wave amplified by the transmitting/receiving means 16, a storage means 22B which stores the result of the processing means 22A while related to the rotation angle of the antenna 13, and a parameter formation means 23a wherein the stored content in the storage means 22b is compared with a pre-set content to calculate the compared result for forming a parameter related to a road-surface roughness distribution.
