Abstract
A method for ascertaining a transverse-velocity-component (TVC) of a radar-target (RT), including: periodically sending modulated, transmitted signals with a transmitting device (TD) having transmission-elements, into a sensing-region of the radar-device (RD), during a measuring-period; receiving a radar-signal (RS) reflected by the RT, using a receiving-device having receiving-elements; transmitting the received (RS) to an evaluation-device and converting it; performing a two-dimensional Fourier-transformation (FT) to generate a velocity-distance spectrum (VDS) of the digital-measured values for each transmission/receiving element; detecting a target reflection of the RT in light of, peak values in a magnitude-spectrum of the VDS; ascertaining a distance of the RT from the RD, and a radial-velocity-component relative to the RD, from the VDS; determining an angle of the RT relative to the antenna; selecting the RT; performing an inverse FT of the target reflection of the RT, and ascertaining the transverse-velocity-component of the RT from the transformed-measured values.
