    摘要： The invention relates to a method for locating an RFID tag (1) using at least one RFID reading device (2). The invention is characterized in that the RFID reading device (2) transmits a query signal (3) which comprises a broadband signal (4); the RFID tag (1) modulates the query signal (3) with a code signal (5) by varying the antenna impedance of the RFID tag and reflects said signal as a reflected signal (6); the RFID reading device (2) receives the reflected signal (6) and obtains the code signal (5) and a scattered broadband signal (7) from the reflected signal; the RFID reading device (2) determines a travel time of the broadband signal (4) by comparing the broadband signal (4) with the scattered broadband signal (7); the RFID reading device (2) determines the distance between the RFID reading device (2) and the RFID tag (1) from the travel time difference.

    摘要： An RFID reader includes a transceiver configured to receive a first radio frequency signal reflected off at least one surface to provide baseline signal information and a second radio frequency signal reflected off the at least one surface and an object to provide further signal information. A comparator is configured to compare the baseline signal information and the further signal information to provide a signal comparison. A processor is configured to detect the presence of the object in accordance with the signal comparison. A determination is made whether the object is in motion in accordance with the signal comparison. The determination whether the object is in motion is made in accordance with a continuous fluctuation of the second radio frequency signal. A determination whether the object is no longer in motion is made in accordance with an ending of the continuous fluctuation of the second radio frequency signal.

    摘要： Provided is a passive radar device capable of extending an observing time for a target and an integration time of a signal with a small calculation amount, sufficiently improving an SNR, and stretching a detection range. The passive radar device includes: a pulse-by-pulse range compression unit for executing cross-correlation processing between a received signal of a direct wave and a received signal of a scattered wave on each of pulses divided by a direct-wave reception unit and a scattered-wave reception unit and calculating a pulse-by-pulse range profile; a block-by-block Doppler processing unit for calculating a first Doppler frequency spectrum by executing pulse-direction Fourier transform in units of blocks each of which groups a plurality of pulses; a Doppler frequency cell-associated range migration compensation unit for compensating a range-direction movement amount with respect to the first Doppler frequency spectrum on a Doppler-frequency-cell-by-Doppler-frequency-cell basis and on a block-by-block basis; and a block-direction Doppler processing unit for calculating a second Doppler frequency spectrum by executing block-direction Fourier transform on an output from the Doppler frequency cell-associated range migration compensation unit.
