Abstract

PURPOSE: To enable measurement of the damping amount of reception due to rainfall with a comparatively simple constitution by controlling the gain of a noise component in accordance with the fluctuation of an input level.
CONSTITUTION: A signal component alone is taken out by the narrow band BPF 4 of a receiver 20 and is given to a composer 12 through the intermediary of a phase shifter 11, while a signal containing the signal component and a noise component taken out by BPF 10 is given to the composer 12. And, only the noise component is taken out from the composer 12 and given to a gain control amplifier 13, and the gain of the noise component is controlled in accordance with a DC component as the fluctuation of the level of the input obtained from the loop filter 9 of the receiver 20, while the output thereof is given to an indicator 15 after being detected 14.
