    摘要: A FM-CW radar device is provided for frequency-modulating a high frequency signal with a modulation signal, transmitting the modulated high frequency signal, receiving a signal reflected by a target object and frequency-modulating the reflection signal with a signal generated by a local oscillator signal source provided by branching a portion of the transmitting signal. A modulator is disposed between a radar transmitting section and a transmitting antenna. The modulator modulates the transmitting signal with a second frequency which is far lower than the radar transmitting frequency and twice as much as the sum or the difference of a Doppler frequency generated by a relative propagation velocity and a beat frequency generated by a propagation delay time. A first frequency converter frequency modulates the received signal reflected by the target object with the local oscillator. A second frequency converter frequency modulates the received signal with the second frequency, the second frequency being far lower than the radar transmitting frequency and twice as much as the sum or the difference of a Doppler frequency generated by a relative propagation velocity and a beat frequency generated by a propagation delay time.

    摘要: An information processing apparatus communicates with a separate passive device, to receive specific information from the separate device. The information processing apparatus includes an antenna, a transmitter and a receiver both coupled to the antenna, and a control unit for controlling the transmitter. The control unit causes the transmitter to transmit a signal at a low transmission power and waits for reception by the receiver of a response signal from the separate device. When the specific information is detected in the response signal, the control unit causes the transmitter to transmit a signal at a high transmission power by raising the transmission power of the transmitter, to thereby enable information to be read from or written to the separate device.

    摘要: An array antenna radar apparatus has a single front end shared by a plurality of antennas, a first switch for cyclically connecting the antennas to the front end at a prescribed switching frequency, and a second switch for cyclically connecting the output of the front end to frequency converters corresponding to the antennas. The frequency converters frequency-convert intermediate-frequency signals of the respective antennas output by the front end to baseband signals at the switching frequency. Phase shifters and amplitude adjusting units apply a phase shift or amplitude adjustment to the outputs of the frequency converters and combine the resulting signals, thereby making it possible to detect a target in a desired direction.
