Hardware system design and analysis for millimeter-wave radar applications
摘要
Abstract
Millimeter-wave radar,as an important sensing technology,is widely used in applications such as autonomous driving,intelli-gent transportation,security monitoring,and industrial inspection,distinguished by its high precision and robust anti-interference capa-bilities.With the continual advancement in the research of power integrity,signal integrity,and thermal stability,significant progress has been achieved worldwide in these domains.However,existing studies predominantly focus on individual aspects,lacking a compre-hensive consideration of the interactions between power noise,signal interference,and thermal effects.This study introduces a unified simulation approach that integrates power,signal,and thermal effects through multi-physics analysis to optimize the overall perform-ance of millimeter-wave radar hardware systems.Additionally,a capacitor optimization strategy is proposed,which involves increasing capacitor configurations within critical frequency bands to effectively enhance power integrity and ensure system stability.Simulation and experimental results demonstrate that the proposed method significantly improves the impedance characteristics of the Power Distribu-tion Network(PDN),reduces power noise and signal interference,and optimizes the system's thermal management.Through these in-novative approaches,this research enhances the comprehensive performance of high-speed circuit systems from multiple dimensions,providing new optimization strategies and methodologies for the design of high-performance hardware tailored for millimeter-wave radar applications.关键词
