摘　　要：目标或其部件微运动产生的微多普勒是目标识别的重要特征,对其进行高分辨测量和微动特征提取是识别的关键。设计了基于连续波体制的微动测量雷达方案,分析设计了收发分离的雷达微带天线,研制了X波段连续波微动测量雷达及其数据采集设备。利用该雷达实测数据采用时频分析工具对人行走的躯体、手、脚运动进行了微多普勒特征分析,实验验证了雷达测量数据的有效性。The micro-Doppler caused by micro-motion of a target or its components is an important feature for target recognition.High resolution Doppler measurement and micro-motion extraction are key steps for recognition.The scheme of continuous wave radar for micro-motion measurement is designed,and the independent received and transmitted micro-strip antenna is analyzed and designed,then an X band continuous wave radar and its data sample device are made.Based on the real measured data of this radar,the micro Doppler features of humans walking gait including body,arms and legs are extracted using a time-frequency analysis method,and the experiments verify the validity of data measured by the radar.
