摘要： A transmission controller 7B is configured to transmit an R/W request signal for requesting transmission of a tag response signal to a RFID tag 1 twice. At this time, a frequency controller 7A controls a PLL section 5A to transmit the R/W request signal via different carrier frequencies. A phase information acquirer 8A detects a phase change amount of the tag response signal that is transmitted via different carrier frequencies. A distance calculator 8B calculates the distance between the reader/writer 2 and the RFID tag 1 on the basis of the phase change amount.

摘要： An RFID tag distance measuring system includes a reader that outputs a predetermined carrier signal to a tag and receives a reflected signal of the carrier signal from the tag. The reader has signal output means for outputting signals at multiple frequencies, which are different from each other, as the carrier signal, a transmitting section that transmits a signal output by the signal output means to the tag, a receiving section that receives reflected signals of the signals at multiple frequencies, which are different from each other, from the tag and estimating means for estimating the distance between the tag and the reader based on the amount of change in phase between the reflected signals received by the receiving section and the carrier signals and the frequencies of the carrier signals. The transmitting section and the receiving section have two pairs of transmit and receive antennas that obtain multiple receive signals in which the strengths of the reflected signals vary differently when the receiving section receives the reflected signals.

摘要： A vehicle control system includes: a vehicle control device that is mounted on a vehicle a portable device that is carried by a user and performs wireless communication with the vehicle control device; and a living body sensor that detects presence of a living body in a vehicle interior of the vehicle. The vehicle control device includes: an in-vehicle transmission unit that transmits a response request signal to the portable device; an in-vehicle reception unit that receives a response signal returned from the portable device in response to the response request signal; and a notification control unit that does not perform notification to the vehicle interior or an outside of the vehicle when the living body sensor detects that the living body is present in the vehicle interior and the in-vehicle reception unit receives the response signal.

摘要： A measurement system and a measuring method are provided in order to make a response and an accuracy of a Doppler system of a 2 frequency CW system or the like compatible with each other. A 2 frequency CW radar measures a relative speed and a distance between one's own vehicle and a measurement object by using a short time period sample data from a receiving signal to output as a high speed measurement result as a measurement of a high speed measurement mode. In parallel therewith, the frequency radar measures a relative speed and a distance between one's own vehicle and the measurement object by using a long period time sample data from the receiving signal to output as a low speed measurement result as a measurement of a low speed measurement mode. As a result, the processing operation apparatus can use the high speed measurement result when a processing of a high response is executed and can use the low speed measurement result otherwise. For example, the processing operation apparatus can also correct the high speed measurement result by using the low speed measurement result. The invention is applicable to a high response system of a pre-clash system or the like.
