RÉSUMÉ

Heavy rains considerably attenuate radio signals transmitted by modern millimeter wave high-speed communication lines. Therefore, this interference in the form of fast and deep changes of rain rates demands further investigations. Industrially manufactured rain gauges are not suitable for these investigations because of their inertia and insufficient precision of measurements. In view of the foregoing a new modification of the tipping-bucket rain gauge is suggested and made in this paper. As the result the precision has slightly improved but the fast-action improved substantially − more than by ten times (up to a few seconds in heavy rains) − owing to considerable diminishing the cuvette size and weight and also due to configuration which removed drop adhesion on its surface. The inclusion of an inexpensive microcontroller into the gauge composition also increased its precision and provided for a better display of rain rate time dependence values on a built-in monitor and interface to a computer for recording.
