    摘要: In accordance with a first aspect of the present disclosure, a localization system is provided, comprising: one or more ultra-wideband (UWB) communication nodes; a controller operatively coupled to the UWB communication nodes; wherein at least one of the UWB communication nodes is configured to perform a first localization operation, wherein said first localization operation is performed in a ranging mode; wherein at least one of the UWB communication nodes is configured to perform a second localization operation, wherein said second localization operation is performed in a radar mode; wherein the controller is configured to perform a predefined function on an output of the first localization operation and an output of the second localization operation. In accordance with further aspects of the present disclosure, a corresponding method of operating a localization is conceived, and a computer program is provided for carrying out said method.

    摘要: An ultra-wideband (UWB) system includes an enclosure, and an ultra-wideband (UWB) transmitter array within the enclosure, the UWB transmitter array having a transmitter component that transmits electromagnetic waves toward a region-of-interest (ROI), the UWB array having a receiver component that receives reflected electromagnetic waves from objects in the ROI and generates object data. The system further includes a radar absorbing material positioned to receive electromagnetic waves transmitted from the transmitter component that are not directed toward the ROI, and a pattern recognition device having a processor configured to process the electromagnetic waves reflected from the ROI and to determine whether an object-of-interest (OOI) pattern is recognized within the object data.

    摘要: An ultra-wideband sensor transmits impulse radio signals at different times and generates respective channel impulse responses that describe a respective reflected signal as a function of a path delay. The channel impulse responses are used to generate a time-variant channel impulse response in which the channel impulse responses are arranged according to the times of transmission of the respective associated impulse radio signals. At least one respective local maximum of the scatter function quantity, characterized by a respective Doppler frequency and a respective path delay, is detected in scatter functions of respective time windows. A predetermined selection method is used to select at least one local maximum as the respective observation maximum to be tracked for motion detection. A signal characteristic of the channel impulse response is generated for the respective observation maximum to be tracked and a predetermined motion detection method detects at least one predetermined movement.

    摘要: According to an embodiment of the present invention: in order to track an accurate location of an asset, an asset location, which is a location of an asset terminal installed in the asset to be tracked, is measured; a relative location of the asset terminal, which is based on a reference terminal, is measured through communication between the reference terminal and the asset terminal; and the asset location is corrected using the relative location. Based on this, the present invention minimizes a measurement error of an asset location, compared to a scheme of measuring an asset location by using only GPS communication.
