    摘要: A system and method for locating radio-frequency identification tags within a predetermined area. The method can incorporate sub-threshold superposition response mapping techniques, alone, or in combination with other methods for locating radio-frequency identification tags such as but not limited to time differential on arrival (TDOA), frequency domain phase difference on arrival (FD-PDOA), and radio signal strength indication (RSSI). The system can include a plurality of antennas dispersed in a predefined area; one or more radio-frequency identification tags; a radio-frequency transceiver in communication with said antennas; a phase modulator coupled to the radio-frequency transceiver; and a system controller in communication with said transceiver and said phase modulator. Calibration techniques can be employed to map constructive interference zones for improved accuracy.

    摘要: A method for operating a domestic appliance includes the steps of: receiving, by means of the domestic appliance, a radio signal from at least one radio transmission source; and determining, by means of the domestic appliance, information on surroundings of the domestic appliance by evaluating a temporal progression of an evaluation signal based on the radio signal and influenced by the surroundings of the domestic appliance. The radio signal is intended for transmission within a local radio network and/or complies with the IEEE 802.11 standard, the IEEE 802.154 standard, or the Bluetooth standard.

    摘要: An in-vehicle radar apparatus includes a transmission and reception means which transmits a radar wave ahead of an own vehicle and receives a reflected wave corresponding to the radar wave from a target; a reception strength detection means which repeatedly detects reception strength of the reflected wave; a distance detection means which repeatedly detects a distance from the own vehicle to the target; an approximate expression calculation means which calculates an approximation expression expressing the reception strength using the distance as a variable from the reception strength repeatedly detected by the reception strength detection means and the distance repeatedly detected by the distance detection means; and a determination means which determines a height of the target from a road surface based on values of coefficients of the approximation expression.

    摘要: There is provided a radar apparatus capable of emitting a transmission wave relating to a transmitting signal which is frequency-modulated, and receiving a reflection wave coming from a target at which the transmission wave is reflected as a receiving signal, to derive at least position information of the target based on the receiving signal. A deriving unit derives a fluctuation value of a signal level relating to the receiving signal for a stationary target among the targets. A calculating unit calculates a fluctuation integrated value integrated by the fluctuation value. A judging unit judges the stationary target as a target other than a control subject if the fluctuation integrated value is below a predetermined threshold.

    摘要: A radar system for recording the environment of a motor vehicle includes at least two transmitter antennas for emitting transmission signals, one or more receiver antennas for receiving transmission signals that have been reflected by objects, and signal processing equipment for processing the received signals. The antennas are arranged so that a phase center of at least one receiver antenna, with regard to a spatial direction R, does not lie outside of phase centers of two transmitter antennas that are offset in this spatial direction. The signals received by this receiver antenna are separated according to the two signal portions respectively originating from these two transmitter antennas.
