Radar sensing of vehicle occupancy

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 an outgoing radar signal;
• receiving, using at least one sensor, at least one sensor signal reflected as a result of the outgoing radar signal,
• obtaining accelerometer data value from at least one accelerometer, said accelerometer data containing information regarding vibration or motion of said automotive vehicle and supplying said accelerometer data to said processing circuitry;
• operating the processing circuitry for generating, based on the at least one sensor signal and on the accelerometer data, one or more occupancy status signals, the occupancy status signal indicating a property related to said at least one occupiable position,
• wherein said generating one or more occupancy status signals comprises applying, based on said accelerometer data, offset removal to said sensor signal to generate a modified signal;
• and
• generating said one or more occupancy status signals based on the modified signals.
