N2 - The paper describes a system aimed at monitoring variations of the atmospheric attenuation in W-band. It consists of an Rx - T x module designed and assembled to be used for operating at 95 GHz frequency. The transmitting part of this module includes W-band sources generating 1 W pulse of duration 100ns. The receiving part consists of the input LNA and balanced mixer driven by LO and IF active detector. Single 48 inches Cassegrain antenna (gain 57dB and 3dB beamwidth = 0.1 degrees) is used for both transmission and reception of the signal reflected from the target placed on the distance about 137m. The azimuth-elevation rotary joint based on overmoded corrugated waveguides was employed in order to provide accurate positioning to this antenna. Examples of monitoring the variations of attenuation during rain fall are presented, too.
