摘要： A method and device for synchronizing a transmitter and a receiver that communicate with each other over a radio interface. A transmission signal is produced with a signal source in the transmitter and is transmitted via the radio interface. A corresponding receiver signal is received in the receiver from the radio interface and is evaluated using a receiver signal source signal from a signal source of the receiver adapted to the signal source of the transmitter. In order to improve synchronization and correction of momentary deviations, the same frequency modulation is applied to the receiver signal source signal, whereby the receiver signal received in the receiver is mixed with the receiver signal source signal to form a mixed signal and the mixed signal is analysed with respect to frequency unbalance.

摘要： According to the invention a reference measurement is carried out without or with only one measurement object and the frequencies of the noise fraction are determined for the resulting frequency spectrum. Discrete measurement values are determined at equidistant sampling points in the form of complex-value overlays of oscillation functions and the noise and useful frequencies and by means of mathematical calculation methods corrected by the noise fractions. The measurement values corrected in this way are then subjected to a known method of frequency analysis.

摘要： FMCW doppler radar, in which a reference signal is generated from the transmit signal via a delay line and a mixer. A measuring signal which is received and mixed with the transmit signal is detected and digitized at the times of the zero crossings of the reference signal. In this way, the measuring signal can be evaluated at time intervals of equal phase of the reference signal. A downstream algorithm enables the generation of a strictly linearly frequency-modulated transmit signal. With this mechanism, phase errors of conventional radar systems are eliminated.

摘要： In a method for determining the position of an object relative to the background with ultrasound, a plurality of ultrasound transducers arranged in a row simultaneously transmit ultrasound in line-shaped fashion in the direction of an object scene and receive both the echo of the signal transmitted by the transducer itself as well as the echoes of the signals generated by the neighboring ultrasound transducers. On the basis of a reference measurement wherein no object is located in the measurement region, the amplitudes and the times of incidence of the echo signals are stored. In the following measurements with an object, the echo amplitudes and the times of incidence of the echo signals are again stored and compared by fuzzy logic to those of the reference measurement. As a result, this supplies the position of the object relative to the background.
