Method and device for detecting precipitation by radar

A device for detecting precipitation in a region monitored by radar beams, the device comprising:

• a transmitting arrangement configured to transmit at least two radar signals;
• an ascertaining arrangement configured to ascertain a first average power of a first backscattered radar signal and to ascertain a second average power of a second backscattered radar signal;
• and
• a detection arrangement configured to detect an existence of precipitation by comparing the ascertained first average power and the ascertained second average power to each other.

A non-transitory computer-readable storage medium storing a computer program, which is executable by a computer, comprising:

• a program code arrangement having program code for performing the following:
• controlling a transmitting arrangement to 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.
