首先引入微多普勒率的概念,然后分析了典型微动目标的微多普勒,并利用时-频分布,提取微动目标的微多普勒特征,基于微多普勒,给出了一种估计运动参数的方法,最后对典型微动旧标的微多普勒进行了仿真,证明了理论分析的正确性.
The conception of micro-Doppler rate was introduced. Micro-Doppler was investigated for typical targets of micromotion. Then time-frequency analysis was used to extract micro-Doppler signature, based on which an approach was proposed for estimating motion parameters. A simulation of micro-Doppler was presented for typical targets of micro-motion. The result of emulation validates the theoretical analysis.
