Claim 15:
16. A method of determining a velocity of raindrops by radar, comprising:
radiating a radar signal from an antenna through a dielectric lens disposed in front of the antenna, wherein the antenna is oriented to the dielectric lens such that radar waves radiated from the antenna pass through the dielectric lens, wherein the antenna is a single antenna;
receiving a reflected radar signal by the antenna, wherein the antenna receives the reflected radar signal from the raindrops through the dielectric lens which focuses a plurality of parallel beams of the reflected radar signal to the antenna; and
determining the velocity of the raindrops based on the received reflected radar signal, wherein the antenna comprises a monostatic radar in which the antenna radiates the radar waves and the antenna receives the reflected radar signal each sharing a common path reducing a viewing angle of the precipitation with respect to the radiation of the radar waves and the receipt of the reflected radar signal, wherein an amount of precipitation is determined based upon a monostatic Doppler shift in which an interference in the reflected radar signal is separated by superposition with the radiated radar waves, and a correlation between velocity and size of the precipitation.
