Abstract

PURPOSE: To measure the amount of rainfall by detecting the attenuating amount of an electromagnetic wave with the amount of the rainfall during its propagation in space.
CONSTITUTION: A millimeter wave transmitting part 1 and a millimeter wave receiving part 2 are provided with a measuring interval for rainfall and the like being separated. The millimeter wave that is transmitted from the transmitting part 1 is received with the receiving part 2. The amount of attenuation is detected in a detecting part 3 for the amount of propagation attenuation. Thereafter, the signal is inputted into a data processing part 4. When there is rainfall, the amount of attenuation in millimeter wave propagation between the transmitting and receiving parts 1 and 2 is increased due to the absorption of the millimeter waves by the rainfall. Because there exists a specific correlation between the intensity of rainfall and the amount of propagation attenuation of the wave, the correlation is stored in a processing part 4 beforehand. The processing part 4 obtains the applicable rainfall intensity based on the inputted amount of attenuation from the detecting part 3. The average rainfall amount in the measuring space is computed by integration operation on the time axis.
