Abstract
A method for determining the functionality of a switchable reception amplifier of a radar system with a transmitting unit, a receiving unit and a voltage-controlled oscillator, wherein, before the radar system is started up, calibration is carried out in order to compensate for a frequency deviation of the frequency emitted by the oscillator. The invention provides for at least one calibration cycle to be run with at least one first signal at a first frequency and one second signal at a second frequency during calibration of the oscillator, wherein the first signal and the second signal are transmitted by the transmitting unit and are received by the receiving unit, wherein the reception amplifier is switched with a switching sequence, which results in amplitude modulation of the first and second signals, and the amplitude modulation is used to determine the functionality of the reception amplifier.
