Abstract

The possibility of reducing the influence of low-frequency noise in the laser phase-frequency rangefinders, which leads to a shortterm instability of converting links of the device has been reviewe. This is achieved through the use of filtering the output signal of the phase-frequency system, the frequency which is proportional to the measured distance. The electronic simulation of converting processes in such system was carried out for which the output signal models in analog and discrete form were received. The results of the simulation allow to choose optimal parameters for a high pass filter according to the allowable value of the error arising from the transition processes in it. By numerical simulations assessment of the random error of the device due to the influence of broadband noise has been carried out. The simulation results are presented as a function of the random error from the signal/noise ratio for the selected filter time constant. References 7, tables 2, figure 1.
