Abstract

The invention relates to a multichannel radio-frequency receiver (1) for electromagnetic waves, having a radio-frequency analogue section (2) which has an input (3) for an electrical signal of a receiving device (4), and having an lower-frequency section (8, 9) which is connected downstream from the radio-frequency analogue section (2) and has a plurality of parallel channels (6b, 6c; 7b, 7c) for respectively different signal strengths and an evaluation circuit, in which a signal divider (5) is provided in the radio-frequency analogue section (2) in order to split the signal in accordance with a predeterminable division ratio into signal elements which can be supplied to radio-frequency analogue channels (6a, 7a), downstream from which the channels (6b, 6c; 7b, 7c) of the lower-frequency section (8, 9) are respectively connected, and the channels (6b, 6c; 7b, 7c) of the lower-frequency section (8, 9) each have an evaluation circuit for detection of the phase and amplitude of the respective signal element.
