We have developed demodulated direct current voltage-based microwave CT (DC-MCT) which is composed on the basis of chirp-pulse microwave CT. DC-MCT was used time domain measurement technique to determine the shortest propagation path between the transmitting-and receiving-antennas. By using standard signal generator with the low phase noise and phase synchronization of signal source, the reconstructed amplitude-and phase-images can be obtained. A study of high speed imaging, the method of measurement and the influence of overshoot characteristics from the low pass filter were examined, then these images were evaluated for the number of rotary scanning of 50 and 72. In addition, for the purpose of improvement of resolution, pursuing a time domain spectrum which gives the max value of amplitude was showed the possibility to improve receiver dynamic range. At the result, this paper shows usefulness of new method for microwave imaging.
