A method for sensing occupancy status within an automotive vehicle using a radar sensor system, the radar sensor system comprising an antenna system, at least one sensor and processing circuitry, the method comprising: illuminating, using the antenna system, at least one occupiable position within the vehicle with continuous wave, CW, signals, characterized in that the CW signals are frequency modulated in time; and in that the method further comprises: receiving, using at least one sensor, at least one sensor signal ( y (t,f 1)... y (t,f n)) resulting from the reflection of the CW signals, the at least one sensor comprising a plurality of receive channels (1...n), where n is an integer and n ≥ 0, each channel having a different frequency (f1...fn); operating the processing circuitry for applying, for each receive channel (1...n), DC offset removal to the corresponding sensor signal ( y (t,f 1)... y (t,f n)) to generate a modified signal ( y' (t,f 1)... y '(t,f n)); and generating, based on the modified signals ( y' (t,f 1)... y '(t,f n)), one or more occupancy status signals (34, 38), the occupancy status signal indicating a property related to said at least one occupiable position. illuminating, using the antenna system, at least one occupiable position within the vehicle with continuous wave, CW, signals, characterized in that the CW signals are frequency modulated in time; and in that the method further comprises: receiving, using at least one sensor, at least one sensor signal ( y (t,f 1)... y (t,f n)) resulting from the reflection of the CW signals, the at least one sensor comprising a plurality of receive channels (1...n), where n is an integer and n ≥ 0, each channel having a different frequency (f1...fn); operating the processing circuitry for applying, for each receive channel (1...n), DC offset removal to the corresponding sensor signal ( y (t,f 1)... y (t,f n)) to generate a modified signal ( y' (t,f 1)... y '(t,f n)); and generating, based on the modified signals ( y' (t,f 1)... y '(t,f n)), one or more occupancy status signals (34, 38), the occupancy status signal indicating a property related to said at least one occupiable position. receiving, using at least one sensor, at least one sensor signal ( y (t,f 1)... y (t,f n)) resulting from the reflection of the CW signals, the at least one sensor comprising a plurality of receive channels (1...n), where n is an integer and n ≥ 0, each channel having a different frequency (f1...fn); operating the processing circuitry for applying, for each receive channel (1...n), DC offset removal to the corresponding sensor signal ( y (t,f 1)... y (t,f n)) to generate a modified signal ( y' (t,f 1)... y '(t,f n)); and generating, based on the modified signals ( y' (t,f 1)... y '(t,f n)), one or more occupancy status signals (34, 38), the occupancy status signal indicating a property related to said at least one occupiable position. applying, for each receive channel (1...n), DC offset removal to the corresponding sensor signal ( y (t,f 1)... y (t,f n)) to generate a modified signal ( y' (t,f 1)... y '(t,f n)); and generating, based on the modified signals ( y' (t,f 1)... y '(t,f n)), one or more occupancy status signals (34, 38), the occupancy status signal indicating a property related to said at least one occupiable position.
