Three Parametric Model Third-Order Software Phase-Locked Loop and its Application in Range Measuring System
Abstract:
In order to improve the precision of side tone range measuring and realize the range measuring process by software, one kind of three parametric model third-order software phase-locked loop (SPLL) is designed based on three parametric loop filter model and the predominant closed-loop poles theory, which can apply the parameter setting principles of the second-order phase-locked loop; this kind of third-order SPLL is realized through C++ language programming and used as the range measuring system’s side tone phase-locked loop(PLL) to process the experiment data. The results indicates that the precision of phase measuring and capture time satisfy the system’s index.
