Talk 1: Long-Time Coherent Integration and Motion Parameters Estimation of Radar Maneuvering Weak Target

Speaker: Qilei Zhang

Affiliation: National University of Defense Technology

Academic title: Associate Professor


It is straightforward to improve the SNR of maneuvering weak target, which is of both low observability and high maneuverability, through increasing observing times and using long-time coherent integration (LTCI) methods. In practice, however, the LTCI is coupled with the motion parameters estimation, and thus is a quite challenging problem. In this talk, the development of LTCI methods is introduced firstly, and then two effective and efficient LTCI algorithms are presented. The first one is developed for wideband radar and based on a time-frequency analyzing method-subband keystone transform and extended LV's distribution (SKT) operations. The second one is developed for high maneuvering targets and based on the Bayesian compressive sensing (BCS) method. 


Qilei Zhang was born in Gansu, China, in 1985. He received the Ph.D. degrees in information and communication engineering from National University of Defense Technology (NUDT), Changsha, in 2014.

His fields of interest include radar target detection, tracking and passive radar system. He is currently an Associate Professor with the College of Electronic Science and Technology, NUDT. He has won 1 ministerial award of first-class for scientific and technological progress, and has published 1 academic monograph and over 60 papers.
