摘要
Abstract
This article first introduces three main requirements of a phase-locked loop(PLL)for Frequency Modulated Continuous Wave(FMCW)radar systems:frequency modulation bandwidth,frequency modulation slope,and linearity.Then,based on highly cited and influential articles from the past decade,it analyzes the advantages and application challenges of digital phase-locked loops(DPLL)in FMCW systems and briefly outlines the existing methods to overcome these challenges.The development trends of phase-locked loops in relation to the three main requirements are summarized,and a new figure of merit definition is proposed to evaluate the performance of PLLs for FMCW systems.Finally,it is pointed out that digital phase-locked loops are a key research direction for developing high-per-formance FMCW systems in the future.关键词
