Precision Industrial Short-Range FMCW Radar Systems. Truncation Measurement Error and Its Minimization

The basic principles of precision frequency range-finder implementation intended for high-accuracy measurement of small and ultra-small distance are considered for industrial automatic control of the technological processes. On the basis of the existing system analysis three groups of such devices are allocated differing by distance measurement accuracy and the implementation complexity. The general approaches are discussed allowing to develop these devices at modern scientific and technological level and to execute its practical implementation.
