Title: POLARIMETRIC RADAR SYSTEM AND METHOD FOR OBJECT CLASSIFICATION AND ROAD CONDITION ESTIMATION IN STATIONARY APPLICATIONS
Abstract:
A polarimetric radar system(10)for object classification and road condition estimation in stationary road applications comprises a radar transmitter unit(12) for transmitting radar waves of at least two different polarizations, a radar receiving unit(22)for receiving radar waves of at least two different polarizations, a radar signal generating unit(32) for generating and providing radar waves to be transmitted by the at least one radar transmitter unit(12),a signal processing circuitry(38) for processing the generated radar waves to be transmitted and the received radar waves and a signal evaluation unit(56). The signal evaluation unit(56) is configured to receive processed signals from the signal processing circuitry(38), to estimate values for a set of predetermined object parameters on the basis of the received processed signals, and to select an object class from a plurality of predetermined object classes 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. Moreover, the signal evaluation unit(56) is configured to provide an information that is indicative of the at least one classified object(86-94).
