Claim 23:
24. A method of detecting external interference signals in a radio frequency (RF) circuit, the method comprising:
generating, by a radar semiconductor chip, a frequency-modulated ramp signal within a predefined radar frequency range, the frequency-modulated ramp signal comprising a plurality of frequency ramps each starting at a respective ramp start frequency and ending at a respective ramp stop frequency, wherein the ramp start frequencies and the ramp stop frequencies of the plurality of frequency ramps define a first frequency range;
receiving, by the radar semiconductor chip, at least one RF signal from an antenna;
detecting, by the radar semiconductor chip, an external interference signal included in the at least one RF signal, the external interference signal being within the predefined radar frequency range;
autonomously adjusting, by the radar semiconductor chip, at least one ramp parameter based on the detected external interference signal; and
autonomously transmitting, by the radar semiconductor chip, the at least one adjusted ramp parameter to a microcontroller.
