Abstract
A polarimetric radar system for detecting and classifying objects positioned in an interior of a vehicle includes a radar transmitter unit for transmitting radar waves of at least two different polarizations, a radar receiving unit for receiving radar waves of at least two different polarizations, a radar signal generating unit for generating and providing radar waves to be transmitted by the at least one radar transmitter unit, a signal processing circuitry for processing the generated radar waves and the received radar waves and a signal evaluation unit that is configured to receive processed signals from the signal processing circuitry, to estimate values for a set of predetermined object parameters on the basis of the received processed signals, and to select an object class upon detecting a match of the estimated values for the set of object parameters with one out of a plurality of predetermined sets of object parameters.
