A UNIFIED ALGORITHM FOR PHASE AND CROSS-TALK CALIBRATION OF POLARIMETRIC DATA - THEORY AND OBSERVATIONS
收藏 引用
IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING 1994年 第1期32卷 89-99页
作者: QUEGAN, S Department of Applied and Computational Mathematics University of Sheffield Sheffield UK
A unified approach to phase and cross-talk calibration of polarimetric data which can be applied to calibrating scattering matrix data or to extraction of the descriptors of distributed targets is described. It relies... 详细信息

PROGRESS IN THE INTERPRETATION OF HF SEA ECHO - HF RADAR AS A REMOTE-SENSING TOOL
收藏 引用
IEE PROCEEDINGS-F RADAR AND SIGNAL PROCESSING 1990年 第2期137卷 139-147页
作者: WYATT, LR Department of Applied and Computational Mathematics University of Sheffield Sheffield UK
When HF radar systems are used for surveillance or tracking of ships or aircraft the strong signal from the ocean surface is termed clutter since it obscures the required signals. Over 30 years ago it was recognised t... 详细信息

SELF-ADAPTIVE NEAR-OPTIMAL CONTROL OF DIFFUSION EQUATIONS
收藏 引用
IEE PROCEEDINGS-D CONTROL THEORY AND APPLICATIONS 1980年 第6期127卷 290-295页
作者: ZINOBER, ASI Department of Applied & Computational Mathematics University of Sheffield Sheffield UK
The self-adaptive near-optimal control of diffusion equations is described. The variable structure feedback design is independent of the initial conditions and the plant parameter values. Rather than identifying the p... 详细信息

Elimination of spiral waves and spatiotemporal chaos by the pulse with a specific spatiotemporal configuration
收藏 引用
Chinese Physics B 2008年 第5期17卷 1925-1934页
作者: 袁国勇 杨世平 王光瑞 陈式刚 Department of Physics Hebei Normal University Institute of Applied Physics and Computational Mathematics
Spiral waves and spatiotemporal chaos are sometimes harmful and should be controlled. In this paper spiral waves and spatiotemporal chaos are successfully eliminated by the pulse with a very specific spatiotemporal co... 详细信息

SEMIVECTORIAL POLARIZED H FIELD SOLUTIONS FOR DIELECTRIC WAVE-GUIDES WITH ARBITRARY INDEX PROFILES
收藏 引用
IEE PROCEEDINGS-J OPTOELECTRONICS 1988年 第5期135卷 333-338页
作者: STERN, MS Department of Applied and Computational Mathematics University of Sheffield Sheffield UK
Following recent successes with semivectorial polarisedẼ field solutions for rib, channel, embedded, and buried waveguides a method is presented for the determination of corresponding polarisedH̃ field modes for simi... 详细信息

Determining the resistance of X-pinch plasma
收藏 引用
Chinese Physics B 2013年 第4期22卷 344-349页
作者: 赵屾 薛创 朱鑫磊 张然 罗海云 邹晓兵 王新新 宁成 丁宁 束小建 Department of Electrical Engineering Tsinghua University Institute of Applied Physics and Computational Mathematics
The current and the voltage of an X-pinch were measured. The inductance of the X-pinch was assumed to be a constant and estimated by the calculation of the magnetic field based on the well-known Biot–Savart’s Law. T... 详细信息
