A Super High Resolution Distance Measurement Method Based on Phase Comparison
Chinese Physics Letters
Phase comparison method can enhance the measurement resolution to 10 −13 /τ in time domain. This method can also be used in distance measurement in the navigation and positioning. We propose a super high-resolution distance measurement based on linear phase comparison method. A high resolution scheme is put forward on the basis of the research of major factors concerning the phase comparison in the distance measurement. Conversion of a high-linearity phase difference to voltage anddoi:10.1088/0256-307x/25/8/024 fatcat:sfz6zfg7yzge5b3pgiotoxqdg4
