摘要： A set value of a frequency setting register is accumulated upon each occurrence of a clock signal, and a waveform memory is read out by using the accumulated value as an address. In the waveform memory, amplitude data of one cycle of the waveform of a burst signal to be generated are stored at fixed phase intervals. The output read out of the waveform memory is converted into an analog signal. A wave-number counter counts the number of times the amplitude data of one cycle is read out of the waveform memory and, when having counted by a preset number of waves, yields a wave-number counting end signal. After the occurrence of the wave-number counting end signal, a phase counter counts clock signals, and, when the count value of the phase counter reaches a value corresponding to a preset end phase, the generation of the burst signal is stopped.

摘要： The reconstruction region of a hologram reconstructed image is segmented. A fast Fourier transform (FFT) is carried out after multiplying the hologram measurement data V(R) by a weighting function. A fast Fourier transform (FFT) is carried out after multiplying the antenna sensitivity inverse matrix A.sup.-1 (R'.sub.a,b) for each segment by inverse propagation function r'.sub.a,b exp(j2.pi.r'.sub.a,b /.lambda.) to find B.sup.-1.sub.a,b (s, t), and then multiplying this by a weighting function. After the two FFT outputs are multiplied by each other, inverse fast Fourier transform (IFFT) is carried out. Compensation is performed for the weighting function and the output is made the segment reconstructed image. In addition, radio hologram observation is carried out at two scan surfaces, a horizontal polarization antenna and a vertical polarization antenna are placed at each scan surface, and the voltage vector distribution received by the antennas is stored. The sizes of the error of the reception antenna sensitivity matrix of the vertical polarization reception antenna and the error of the reception antenna sensitivity matrix of the horizontal polarization reception antenna are found, and the received voltage vectors and reception antenna sensitivity inverse matrices are selectively used to find and visualize the three wavesource current vector components.

摘要： Radio waves having frequencies f.sub.1 and f.sub.2 are radiated to the premises where a wireless LAN is to be constructed. The radio waves of f.sub.1 and f.sub.2 are received by an antenna for scanning the observation plane and a fixed antenna, respectively. Then, the radio wave holograms of the respective radio waves are produced, from which are constructed radio wave source images separated into respective paths. The difference between these source images is found, and then the amplitude and the delay for each path are found. A propagation time response function x(t) of each path is found from the corresponding amplitude, delay and the directivity characteristics of the corresponding antenna, and then the real part and the imaginary part of each time response function are convoluted into a modulated carrier wave signal y(t). The convoluted results are multiplied by the in-phase component R.sub.f and the quadrature component R.sub.f.spsb.* of an unmodulated carrier wave, respectively. Then, the multiplied results are summed to obtain a demodulated base band signal .gamma. (t). Also, a radio wave delay time of each secondary radio wave source image to the primary wave source is found. The radio wave source image is re-positioned in a three-dimensional absolute coordinate using the radio wave delay time. At an arbitrary position in the absolute coordinate, the radio waves from the respective radio wave source images are composited to find the strength. Also, a mean delay and a standard deviation of the delay are found from the delay times and the strength attenuations in accordance with the distances to each radio wave source image.

摘要： A non-contact type wave signal observation apparatus measures transfer functions of a distributed constant network. A signal is input from a network analyzer to the network to be measured. Electromagnetic waves radiated from the network are received at each observation point on an observation plane arranged in a manner facing the network. The received signals are input to the network analyzer. The transfer functions between an input terminal of the network and each observation point are measured by the network analyzer. The measured transfer functions are converted by an inverse-Fresnel transformer and are stored in memories. The stored data is specified by a control unit and is displayed on a display unit. The stored data can be converted by an inverse-Fourier transformer and is displayed on the display unit as waveforms. Further aspect of the apparatus is, by a non-contact method, to measure signals of a distributed constant network, to determine states of electromagnetic wave in the space, to decrease the amount of calculations in a hologram reconstruction process, and to display a complex three dimensional illustration for a holographic radar.

摘要： In an impedance and transfer characteristic measuring apparatus sine-wave and cosine-wave data are produced using data obtained by accumulating a fixed phase value in synchronism with a clock signal and the sine-wave data is provided to a device under test after D-A conversion. Multiplied outputs are obtained by multiplying type D-A converting part which D-A converts the sine-wave data and the cosine-wave data, using two signals related to an item of measurement of the device under test as analog multiply inputs therefor. An intergration control signal of a predetermined level is generated by a signal generating part for the half-cycle period of a sine-wave test signal in synchronism with a measurement start signal. For the period during which the intergration control signal is yielded the multiplied outputs are respectively integrated in an integration circuit part to thereby obtain vector-detected outputs. The detected outputs are A-D converted, and based on the digital detected outputs, a calculating part performs calculations related to the item of measurement.

摘要： In order to implement novel utilization methods, implementation of a low power consumption and high sensitivity RF receiving system is desired. A microwave frequency band stub resonance booster circuit characterized by boosting the amplitude of an RF signal in a passive operation by resonating in series a 0.2 pF to 0.01 pF micro-capacitor element with a λg/2 open stub element to perform impedance conversion of the input RF signal is used. In addition, since a capacitor which has been conventionally inserted in order to repeat charging and discharging of the RF signal by using two diodes becomes useless by putting a DC resonant component of resonant-boosted output into an open state when voltage-doubling and rectifying the resonant-boosted RF signal, rectified output can be obtained and high-sensitivity reception and detection of the RF signal becomes possible without being affected by the capacitor which imparts comparatively large insertion loss.

摘要： The present invention aims to overcome the drawback with conventional RFID tag devices having a short communication range, and expand the communication range to several times or more that in the conventional scheme. The conventional scheme is based on equilibrium feeding/equilibrium modulation (a two-terminal circuit for antenna operation), whereas the present invention is based on disequilibrium feeding/equilibrium modulation (a three-terminal circuit for antenna operation). The conventional scheme is based on simple rectification of received RF signals, whereas the present invention employs a circuit based on a combination of a stub resonance-based, impedance transformation boosting scheme and a ladder boosting scheme. The conventional scheme is based on ASK or BPSK modulation, whereas the present invention is based on passive modulation, but can employ a QPSK modulation circuit.
