High-Precision Wideband Phase-Derived Velocity Measurement for Micro-Motion Extraction
《Journal of Beijing Institute of Technology》2017年第1期106-114,共9页Yuan Jiang Huayu Fan Quanhua Liu Xinliang Chen 
Supported by the National Natural Science Foundation of China(61301189);111 Project of China(B14010)
A phase-derived velocity measurement method is proposed in a wideband coherent system,based on a precise echo model considering the inner pulse Doppler effect caused by fast moving targets.The Cramer-Rao low band of v...
