Technical Electrodynamics| Резюме: | In paper refers to the block scheme of a laser rangefinder (RF) system. Area of use review RF system to determinate the distances or removing diffusion object. In proposed system sampling the reference and test signals is performed at the intermediate frequency with subsequent calculation phase shift. Considered significant drawbacks of usual put in practice phase detect methods for RF system. Was show the optimum phase meter phase detector scheme can be realized using the discrete Hilbert transform. Composed the scheme based on the discrete Hilbert transform for detect phase shift in RF system. Developed special software in LabVIEW for modeling and study the operation of the proposed structure of the phase detector. As a result of research was analysis an according to the estimates of errors that arise during aliquant sampling interval and the period of the sampled signal and individual discrete random deviation from ideal value.
