Abstract:
This invention provides a device for measuring precipitation by means of radar, comprising an antenna adapted to transmit and receive radar waves and a dielectric lens, the antenna being oriented to the dielectric lens such that radar waves radiated from the antenna pass through the dielectric lens. Furthermore, it is provided a method of determining a velocity of raindrops by radar, comprising the steps of: radiating a radar signal by means of an antenna, receiving a reflected radar signal by said antenna and determining the velocity of the raindrops based on the received reflected radar signal wherein a dielectric lens is disposed in front of the antenna such that the radiated radar signal passes through the dielectric lens.
