摘要： The invention relates to a velocity determination apparatus (1) for determining a velocity of an object(2). A Doppler frequency measuring unit is adapted to measure Doppler frequencies in at least three different frequency directions, wherein a Doppler frequency calculation unit is adapted to calculate a Doppler frequency for a calculation frequency direction being similar to one of the at least three different frequency directions depending on the Doppler frequencies measured for at least two further frequency directions of the at least three different frequency directions. The velocity can then be determined depending on the calculated Doppler frequency and the measured Doppler frequencies. Since in the calculation frequency direction the measured Doppler frequency is not needed for determining the velocity,a reliable velocity can be determined also in the calculation frequency direction, even if the measurement of the Doppler frequency in this calculation frequency direction is disturbed.

摘要： The present disclosure describes methods for measuring and analyzing the complex parameters of multitude of RF/MW signals, occurring in various points of the energy system. The application also describes embodiments of RF and mixed-signal hardware, implementing the invented methods.
The methods deploy and process multi-tone signals in the channels of the RF/ MW energy system. The multi-tone signals consist of a high power signal, and one or multiple small-signal tones. The later ones are phase or frequency modulated with signals, either harmonic ones or signals with different waveforms), which are unique and channel-specific. The RF signals, sampled in different points of the system, could comprise the contributions of a multitude of channels. The contributions of the individual channels are differentiated, based on the applied modulation frequencies, and further analyzed, using appropriate demodulation and parameter estimation techniques. The magnitudes of the applied small-signal tones are, at least, in an order of magnitude lower than the large power ones and have insignificant impact on system's operation. Therefore, the disclosed methods can be applied both during the characterization phase of the RF/ MW energy applications, and in its "real-life" operation.
