    摘要: A radar system for determining a distance to another radar system includes a transceiver. The transceiver transmits a first Frequency Modulated Continuous Wave, FMCW, radar signal. The first FMCW radar signal includes a first sweep profile. The transceiver is receives a second FMCW radar signal. The second FMCW radar signal includes a second sweep profile which differs from the first sweep profile. The radar system further includes a mixer which generates a beat signal based on the first and second FMCW radar signals. The radar system further comprises a deskewing unit which deskews the beat signal by matching the sweep profiles of the first and second FMCW radar signals. Further a method for determining a distance between radar systems, a system for determining a distance between first and second radar systems and a method for determining a distance between first and second radar systems.

    摘要: Methods, systems, computer-readable media, and apparatuses for radar processing based on a combination of analog beamforming, digital beamforming, and virtual arrays are described. In certain embodiments, a radar receiver receives signals simultaneously transmitted, i.e., concurrently, from a radar transmitter. Each transmitted signal corresponds to the same transmit signal, but with a respective phase being applied. The radar receiver generates, based on the received signals, a virtual array response corresponding to an array of virtual antennas. The virtual array response covers a subset of directions within a field of view to be scanned. In some embodiments, the transmissions from the radar transmitter are generated using analog beamforming, and the virtual array response generated using digital beamforming. In other embodiments, the transmissions from the radar transmitter are generated using digital beamforming, and the virtual array response generated using analog beamforming.

    摘要: A dual-band antenna panel comprises a plurality of dual-band radiating cells operating independently for a first frequency in a first frequency band and a second frequency in a second frequency band, the first frequency band being higher than the second frequency band, each of the radiating cells exhibiting a distinct feed to the first and to the second frequency. The antenna panel comprises radiating cells disposed according to a mesh dimensioned with respect to the first frequency band, and wherein the feeds to the second frequency of the radiating cells are clustered in packets within combiners having a single feed.

    摘要: A method for locating a target comprises: a) receiving, by means of N≧1 receivers, opportunity radioelectric signals transmitted by M≧1 transmitters and reflected by the target, with N·M≧3, or at least one transmitter being situated out of sight of at least one receiver; b) receiving, by means of a data transmission link, one or more reference signals, representative of the radioelectric signals transmitted by each transmitter situated out of sight of at least one receiver; and c) determining the position of the target on the basis of the radioelectric signals and of the reference signal or of the reference signals. An application of the method to the primary monitoring of air traffic, a multistatic radar system for the implementation of the method, and a system for monitoring air traffic comprising a multistatic radar system are provided.

    摘要: This disclosure provides a tracking information control device. The device includes a receiver for receiving, from two radar devices, data relating to a target echo received by a radar antenna of one of the radar devices, and data relating to a target echo received by a radar antenna of the other radar device, the data being obtained from tracking the target echoes, respectively, a determiner for determining whether the target echoes indicate the same target object, an ID applier for applying the same ID to the target echoes when the determiner determines that the target echoes indicate the same target object, and a transmitter for transmitting the same IDs to the radar devices in order to inform whether the target echoes displayed by the radar devices, respectively, indicate the same target object.
