Inverse synthetic aperture radar imaging of target with complex motion
Radar imaging has the characteristic of all-weather, day/night and long range, and has great value in civilian and military applications. Due to the dissimilarity of the Radar’s working mechanism and imaging mode, imging Radar can be divided into two categories-inverse synthetic aperture Radar (ISAR) and synthetic aperture Radar (SAR). In ISAR imaging, the echo after motion compensation can be characterized as the model of multi-component polynomial phase signal (PPS), and this is a typical kind of nonstationary signals. When implement the ISAR image of a target, this model can be approximated logically according to the movement character of the target, and the quality of the Radar images lies on the signal processing technique. That is to say, the quality of the Radar images can be improved greatly by the signal processing methods. This report divides the echo of the target into three categories from the aspects of parameter estimation and time frequency distribution, they are the constant amplitude polynomial phase signal (PPS) model, time varying amplitude PPS model and directly obtaining the time frequency structure of the signal based on the time frequency methods. New algorithms are presented in signal processing corresponding to the three models above in order to improve the quality of the Radar images.
Yong Wang was born in 1979. He received the B. S. degree and M. S. degree from Harbin Institute of Technology (HIT), Harbin, China, in 2002 and 2004, respectively, both in electronic engineering. He received the Ph. D. degree in information and communication engineering from HIT in 2008.
He is currently a Professor with the institute of electronic engineering technology in HIT. His main research interests are in the fields of time frequency analysis of nonstationary signal, radar signal processing, and their application in synthetic aperture radar (SAR) imaging.

From Concept to Prototype: NI software defined radio platform and 5G overview
National Instruments is collaborating with top researchers focused on 5G wireless communications. The graphical system design approach combines LabVIEW Communications System Design Software with SDR Platform to help researchers innovate faster. By using this approach, engineers can reduce the time form theory to results by testing their designs in a real-world environment. In this session, you will learn the key elements of NI SDR platform and four potential technologies to make 5G a reality, which include massive MIMO, densification of network, new waveforms and mmWave communications.
