Research Areas

Xuan Li is a researcher at the Institute of Acoustics, CAS, a post professor at the University of Chinese Academy of Sciences, and a member of CAS Youth Innovation Promotion Association. She received her B.E. degree in Automation from Tsinghua University in 2005, and her Ph.D. degree in Engineering from the University of Chinese Academy of Sciences in 2010. In recent years, she has presided over many projects, including the National Natural Science Foundation of China (NSFC) project, CSTC project, CAS Defense Innovation Project,etc. She has co-organized the course "Hydroacoustic Modeling and Sonar System Analysis" in NUST since the fall semester of 2015. In recent years, she has published more than 30 papers in famous academic journals and international conferences at home and abroad, and granted 5 patents. Her research interests are mainly in the field of hydroacoustic signal processing, including joint underwater multi-platform detection, target parameter estimation, hydroacoustic array signal processing, etc. She has proposed algorithms for hierarchical underwater network structure, AUV multi-array data fusion, waveform diversity transmitter and high-resolution parameter estimation.


Experience

The research area is mainly focused on array signal processing and intelligent hydroacoustic signal processing, including joint underwater multi-AUV detection, high-resolution parameter estimation, noise cancellation, etc.
