“…According to the numerical results, the variation of displacement resolution against the key parameters including the laser wavelength, the detection distance, the laser linewidth and the signal power. It reveals that the phase fluctuation has a significant effect on the power spectrum of photocurrent [13]. Besides, both the probability density distribution of phase noise and displacement resolution have heavy dependence on laser oscillation line shapes.…”

This paper introduces experimental results of a laboratory scale laser Radar. A computer-controlled laser radar system for measuring moving object velocities using both CO2 laser and laser diode was constructed. Different moving objects with different velocities were used. Furthermore, Doppler Shifts, modulation frequencies and laser wavelengths were transferred to a personal computer (PC). From the previous parameters, the pc was able to present target velocities. A special software and the relevant electronic card (type HP-Gp-lb-designed for spectrum analyzer) were used for noise cancellation and for measuring moving object velocities. We used heterodyne detection technique to detect weak signals.
