内容記述 | The purpose pf this paper is to develop equipment for measuring depth. This equipment consists of an optical transmitting and receiving unit and a base-band processong unit. We have studied the base-band unit using an I-Q demodulator and a one-chip microcomputer, which is suitable for realizing smaller size and more flexible operation than a conventional unit. A table look-up method with an I-Q selected-phase-area unequal-interval sampling technique is proposed to detect phase information, which corresponds to snowfall depth. Through analysis using a computer simulation, we show that the proposed method can give the maximum phase-error below 0.5 degrees on a 12-bit A/D converter, even if a receiving signal level has fluctuation of 15 dB. Moreover, we experimentally estimate the phase-error performance by testing the implemented base-band unit. | |||||
