Abstract
The invention relates to a multichannel radio-frequency receiver for electromagnetic waves, having a radio-frequency analogue section, which has an input for an electrical signal from a reception device, and having a lower-frequency section, which is connected downstream of the radiofrequency analogue section and has a plurality of parallel channels (6b, 6c; 7b, 7c) for in each case different signal levels and an evaluation circuit, in which, in the radiofrequency analogue section 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 are respectively connected, and the channels (6b, 6c; 7b, 7c) of the lower-frequency section each have an evaluation circuit for detection of the phase and amplitude of the respective signal element.
