Qiang Guo was born in 1972. He<br />
received the B.S., M.S. and Ph.D. degree<br />
from Harbin Engineering University in<br />
information and communication<br />
engineering in 1994, 2003, and 2007,<br />
respectively. He is now an associate<br />
pr<strong>of</strong>essor <strong>of</strong> information and<br />
communication engineering at Harbin<br />
Engineering University and a postdoctoral<br />
fellow <strong>of</strong> control science and engineering<br />
at Harbin Institute <strong>of</strong> Technology (HIT), China. His current<br />
research interests include radar signals sorting and recognition.<br />
More complex and dense pulses environments in modern<br />
electronic warfare present a severe challenge to the problem <strong>of</strong><br />
radar signal sorting. Based on fractal theory and Hilbert-Huang<br />
Transform (HHT), he presented a new feature extraction<br />
method for radar pulse signal sorting. It used structure function<br />
and empirical mode decomposition to process 2-dimension<br />
feature information, which constituted carrier frequency and<br />
time-<strong>of</strong>-arrival. The same scheme also applied to the analysis<br />
and extraction <strong>of</strong> hidden periodically changing features—G<br />
features. Experiment results show that the method can<br />
effectively identify the agile frequency in periodically changing<br />
radio frequency signals <strong>of</strong> complex pulse environment,<br />
therefore provides a new feature for signal sorting <strong>of</strong> interleaved<br />
radar pulse sequences.<br />
He received the national 100 excellent doctor degree<br />
dissertation candidate nomination in 2009. He is now Academic<br />
Degree & Graduate Education Evaluating expert <strong>of</strong> MOE.<br />
Yajun Li was born in 1983. He<br />
respectively received the B.S., M.S. degree<br />
from YaTai University and Harbin<br />
Engineering University in information and<br />
communication engineering in 2008, 2011.<br />
He is now an Ph.D. at Harbin Institute <strong>of</strong><br />
Technology (HIT), China.<br />
His current research interests include<br />
radar signals sorting and detection. At<br />
present, he has already published seven articles(EI index).<br />
Changhong Wang was born in 1961. He<br />
received the B.S. the M.S. and Ph.D. degree<br />
from Harbin Institute <strong>of</strong> Technology in<br />
1983, 1986, and 1991, respectively. He is<br />
currently a pr<strong>of</strong>essor and Ph.D. student<br />
supervisor <strong>of</strong> Harbin Institute <strong>of</strong><br />
Technology.<br />
His research interests are mainly in<br />
inertial navigation, precise servo control<br />
system, and robust control.
