Abstract

A method for testing at least one reception path in a radar receiver is provided. The reception path contains a mixer and a downstream signal processing circuit. The method involves injecting a test signal into the reception path, so that at least a first test tone having a frequency in a passband of the signal processing circuit and a second test tone having a frequency outside the passband are present on the reception path downstream of the mixer. Further, the method involves tapping off a baseband signal, generated by the signal processing circuit, from the reception path, the baseband signal being based on the test signal.
