An Efficient Simulated Sea Slope Model for Backscattering from a Non-Gaussian Sea Surface
《Chinese Physics Letters》2009年第9期129-132,共4页张民 陈珲 周平 张向阳 
Supported by the National Natural Science Foundation of China under Grant No 60871070, the National Pre-research Foundation and the Foundation of National Electromagnetic Scattering Laboratory.
Based on the double superimposition model, a sea slope model is obtained on the basis of the generated oceanic surface instead of being assumed as a Gaussian distribution model. Then, a summation formula of the backsc...

Scattering from Alpha-Stable Non-Gaussian Distributed Surfaces
《Chinese Physics Letters》2007年第1期97-100,共4页任玉超 郭立新 吴振森 
Supported by the National Natural Science Foundation of China under Grant No 60571058, the National Defense Foundation of China.
The scattering problem of alpha-stable non-Gaussian distributed rough surfaces is studied. The alpha-stable non-Gaussian distribution is used to describe the surfaces that exhibit sharp and sparse peaks, not usually s...
Modified Two-Scale Model for Electromagnetic Scattering from the Non-Gaussian Oceanic Surface被引量:2
《Chinese Physics Letters》2005年第11期2808-2811,共4页王运华 郭立新 吴振森 
Based on the skewness of sea waves, a modified two-scale model is developed for the non-Gaussian sea surface scattering. In this new model, a complementary term is added to the first-order scattering coefficient of th...

Non-Gaussian Pulse Propagation and Pulse Quality Factor Using Intensity Moment Method
《Chinese Physics Letters》1999年第6期415-417,共3页LIN Guo-cheng SUI Cheng-hua LIN Qiang 
Supported by Zhejiang Provincial Natural Science Foundation of China under Grant No.RC98029.
The propagation of ultra-short light pulses with nonlinear chirp and arbitrary amplitude profile is treated by using first-order and second-order intensity moments in temporal domain.A generalized pulse complex parein...
