Autor: Chen Shuo, Luo Chenggao, Deng Bin, Qin Yuliang, Wang Hongqiang, Zhuang Zhaowen

Publikováno v: Leida xuebao, Vol 7, Iss 1, Pp 127-138 (2018)

Terahertz coded-aperture imaging follows the basic principles of optical coded-aperture imaging and microwave coincidence imaging and is a novel imaging technique. Herein, the wave spatial distribution or illumination pattern is usually obtained by a

Autor: Jiang Yanwen, Deng Bin, Wang Hongqiang, Qin Yuliang, Zhuang Zhaowen

Publikováno v: Leida xuebao, Vol 7, Iss 1, Pp 139-146 (2018)

To improve the imaging accuracy of Interferometry Inverse Synthetic Aperture Radar (InISAR), in this paper, we propose a novel method based on the joint processing of dual-frequency data. First, we divide the radar echo into two parts in the fast-tim

Underwater Source Localization Using TDOA and FDOA Measurements with Unknown Propagation Speed and Sensor Parameter Errors

Autor: Zhang, Bingbing, Hu, Yongchang, Wang, Hongyi, Zhuang, Zhaowen

Publikováno v: IEEE Access 6(1):36645-36661, 2018

Underwater source localization problems are complicated and challenging: a) the sound propagation speed is often unknown and the unpredictable ocean current might lead to the uncertainties of sensor parameters (i.e. position and velocity); b) the und
