Shanghai Jiao Tong University

I am currently a third-year Ph.D student in the School of Electronic Information and Electrical Engineering at Shanghai Jiao Tong University of China, where I am supervised by Prof. Junfa Mao (Academician of CAS, IEEE Fellow) and Prof. Changzhan Gu. Before that, I got my bachelor’s degree at Xidian University, supervised by Prof. Ying Liu (IEEE Fellow) and Prof. Shuai Zhang. During my undergraduate studies, I ranked first in my major, achieved the highest score since the establishment of the major, and was directly admitted to the Ph.D.

I have received over ten honors and awards, including the National Scholarship, Outstanding Graduate of Shaanxi Province, the Jiachi Yang Academician Scholarship and so on. Moreover, I have received five times’ Best/Excellent Paper Awards from IEEE conferences as an author/coauthor. Additionally, I have won nine provincial and higher-level awards in competitions, such as the “Challenge Cup” National College Student Academic and Technology Competition, the National/International Mathematical Modeling Competition, the National College Student Computer Design Competition, the National College Student Mathematics Competition, among others.

My research interests include 4-D millimeter-wave MIMO radar systems and sensing algorithms. I have published more than 10 papers and I have been involved in projects such as National Key R&D Program of China and Natural Science Foundation of China.

Frequency-Domain Leakages and Stationary Clutters Cancellation Technique With a K-Band Short-Range End-to-end Sparse MIMO FMCW Radar System

Jiayu Zhang, Zhiwei Zhang, Yuchen Li, Changzhan Gu* and Junfa Mao

IEEE Transactions on Microwave Theory and Techniques, 2025

  • This technology can be applied to MIMO FMCW radar for RF leakage and static clutter cancellation.
  • The frequency-domain characteristics of the intermediate frequency (IF) signal are used to effectively remove interference targets such as leakage and static clutter, enabling accurate target detection. This approach is validated using a custom-designed 24 GHz sparse MIMO FMCW radar system and applied to multi-person point cloud trajectory detection in indoor environments.

77-GHz MIMO FMCW radar system for real-time human motion tracking

  • This system uses the Andar ADT3102 radar to detect human target within the FOV and enables the fan to rotate in real-time following the human target.
  • This system detects the range and angle information of the target and transmits them to the STM32 via the serial port. The STM32 generates corresponding PWM waves to control the motor's real-time rotation based on the target's spatial information, with an accuracy within 2.2°. This enables accurate real-time target positioning and tracking.
