Abstract: 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.

Abstract: An integrated acoustooptical component for frequency-shifting optical frequencies is proposed, in which two separately guided optical waveguides exhibit an optical coupling region, which is designed in the manner of a directional coupler and in which the two optical waveguides exhibit a small spacing from one another generating an optical coupling. The acoustic waves of a sound generator propagate in the longitudinal direction over the coupling region. The two optical waveguides exhibit differing propagation constants for light. If, for example, light of mode a is injected into the optical waveguide and if the sound generator is energised, then the photons of mode a are scattered at the phonons of the acoustic waves and converted into mode b of the optical waveguide, where they can propagate. This gives rise to a frequency shifting. Accordingly, the acoustooptical component includes a frequency shifter and at the same time a coupler, which can be used for beam splitting and/or as an optical switch.
