Apparatus

Abstract

The present disclosure is related to a frequency modulated continuous wave (FMCW) radar system including: a transmitter circuit configured to transmit FMCW chirps at a chirp frequency, wherein the transmitter circuit is operable in either: an acquisition phase, during which the transmitter circuit is configured to change the frequency of an output signal from a first frequency to a second frequency; or a reset phase, during which the transmitter circuit is configured to change the frequency of the output signal from the second frequency to the first frequency; where an FMCW chirp is defined by the output signal over the course of one acquisition phase and one reset phase; a receiver circuit, the receiver circuit comprising an analogue to digital converter, ADC; and a controller configured to: enable the ADC during each acquisition phase of the transmitter circuit, and disable the ADC during a reset phase of the transmitter circuit.
