Abstract
A method for detecting precipitation in a region monitored by radar beams includes ascertaining a first average power of a first backscattered radar signal, ascertaining a second average power of a second backscattered radar signal, and detecting an existence of a homogenous medium when the average powers conform.

14. A method for detecting precipitation in a region monitored by radar beams, the method comprising:
-
transmitting at least two radar signals; ascertaining a first average power of a first backscattered radar signal; ascertaining a second average power of a second backscattered radar signal; and detecting an existence of precipitation by comparing the ascertained first average power and the ascertained second average power to each other. - View Dependent Claims (15, 16, 17, 18, 20, 21, 22, 23)

19. The method as recited in claim 19, wherein the object-free section is determined by analyzing the spectral power densities of the backscattered radar signals, the object-free section corresponding to a shared subsection of the spectral power densities in which none of the spectral power densities has a peak that projects above a background noise of the respective spectral power densities.
