  • Patent number: 9841449
    Abstract: A system and method corrects the phase of measurement signals obtained from remote heads during testing of a device. A first signal is transmitted along first and second transmission lines to respective remote heads. A shunt switch is connected between a remote end of the first transmission line and a first remote head, and another shunt switch is connected between a remote end of the second transmission line and a second remote head. The shunt switches in a first configuration respectively reflect the first signal back to a phase measurement apparatus as first and second reflected signals. The phase measurement apparatus determines a first reference phase and a second reference phase respectively based on the first and second reflected signals. A compensation unit compensates phase of the measurement signals based on the first and second reference phases.

  • Patent number: 8884811
    Abstract: The present invention relates to a method for separating transmitted signals in radar systems and an associated radar system. In the method, the signals for transmission are shared among multiple subcarriers by means of OFDM, which subcarriers are assigned to the transmitting antennas according to a distribution scheme. In this distribution scheme, each subcarrier is assigned to one transmitting antennas only. The subcarriers assigned to a given transmitting antenna are spread over the entire signal bandwidth. In this way, very high dynamics may be achieved while retaining complete orthogonality of the signal paths.

  • Publication number: 20120076190
    Abstract: The present invention relates to a method and also a device for digitally processing OFDM signals which are emitted by a transmission apparatus with modulation symbols as information carriers, reflected at one or a plurality of objects at least to some extent and received by a receiving apparatus. The modulation symbols are extracted without prior channel equalisation from the OFDM signals received and the extracted modulation symbols are normalised by a complex division to the respectively transmitted modulation symbol. The radar analysis for determining the distance and/or determining the speed of the objects then takes place on the basis of the normalised modulation symbols. With the method and the device, on the one hand, both distance and speed of the objects can be determined independently of one another. On the other hand, the method works very reliably, as it is not influenced by the transmitted information.
