摘要： In a method for frequency matching in an FMCW radar sensor, a plurality of frequencies, which are derived on various modulation ramps, and which respectively are shown by the radar sensor in a d-v space as geometrical locations, represent possible combinations of a distance d and a speed v of the respective object. In order to identify the objects located on the various modulation ramps, coincidences between the geometrical locations which belong to frequencies derived on various modulation ramps are searched for. The search for coincidences is initially restricted in a first step to a subspace of the d-v space, and in a subsequent step, the search is extended to other regions of the d-v space, while suppressing the frequencies that are associated with the objects found in the first step.

摘要： An optical arrangement for direction dependent coupling out of light comprises a first and a second polarization converter each for converting the state of polarization of light received in a predetermined way. A polarization dependent coupling device is adapted for coupling out a portion of the light received, whereby the ratio of the coupled out portion substantially depends on the state of polarization of the light received. The polarization dependent coupling device is arranged between the first and the second polarization converters, and the optical arrangement receives from different sides light beams propagating in different directions. The characteristics of the first and the second polarization converters are adapted such that the polarization dependent coupling device receives light beams propagating with different states of polarization in the different directions.
