A method for occupancy detection for at least one vehicle seat, using at least one transmit antenna and a plurality of receive antennas, includes: emitting a detection signal with each transmit antenna onto at least one vehicle seat, which detection signal is a frequency-modulated continuous-wave radar signal, and receiving with each receive antenna a reflected signal; recording sample data representing the reflected signal, the sample data having M channels, with M=N1·N2, where N1 is the number of transmit antennas and N2 is the number of receive antennas; for each channel, removing a component from the sample data that corresponds to a reflection from a static object; and applying a frequency estimation method to the sample data to at least implicitly determine at least one angle of arrival θcorresponding to a position of an occupant on a vehicle seat.

A polarimetric radar system for object classification and road condition estimation includes a radar transmitter unit for transmitting radar waves of different polarizations, a radar receiving unit for receiving radar waves of different polarizations, a radar signal generating unit for generating and providing the radar waves to be transmitted, a signal processing circuitry for processing the generated and received radar waves, and a signal evaluation unit. The signal evaluation unit receives processed signals from the signal processing circuitry, estimates values for a set of predetermined object parameters on the basis of the received processed signals, and selects an object class from a plurality of predetermined object classes upon detecting a match of the estimated values with one out of a plurality of predetermined sets of object parameters. The signal evaluation unit is configured to provide information that is indicative of the at least one classified object.

A radar sensor system and a method for detecting an occupancy in an interior of a vehicle and with vital sign monitoring. The radar sensor system includes a radar transmitting unit, a radar receiving unit and a signal processing and control unit. The method includes: transmitting a radar wave towards a scene within the vehicle interior, receiving at least one radar wave that has been generated by reflection of the transmitted radar wave, decomposing the received radar wave into range, Doppler and angular information, quantifying and tracking a movement in each region of interest by angular gating and range gating, detecting and monitoring vital signs of occupants in each region of interest, and determining whether quantified and tracked movements in the scene are related to an occupant or to external or internal disturbances, based on a fulfillment of at least one predefined condition concerning the and/or the detected vital signs.
