First Claim
Patent Images
1. 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.
