地海交界分区域复合粗糙面的布儒斯特效应研究
Brewster effect from composite rough surface of ground and sea in adjacent region
摘要
Abstract
Based on modeling theory of random rough surface,Brewster effect of composite rough surface of adjacent region between ground and sea is studied.The Monte Carlo method is applied to construct composite rough surface.Gauss spectral function is introduced to generate ground rough surface,and Pierson Moskowitz(PM) spectral function is used to simulate actual sea rough surface.Weighted inverse tangent function is presented to filter in order to smooth the borderline between ground and sea.The geometrical model of composite rough surface of adjacent region between ground and sea is established.The couplings of facets in respective region and facets of region near borderline are considered,and an iterative physical optics(IPO) based on facets of composite rough surface of ground andsea in adjacent region is presented.The electromagnetic scattering in the specular direction of composite rough surface of ground and sea in adjacent region is quickly calculated.The influences of root mean square and correlation length of ground rough surface,and wind velocity and wind direction of sea rough surface on Brewster effect are discussed.The "Brewster fusion effect" of composite rough surface of ground and sea in adjacent region is discovered.And the "fusion" phenomenon of Brewster angle is more remarkably affected by root mean square of ground rough surface and wind velocity of sea rough surface.This research provides theoretical basis for detection of actual environment of ground and sea in adjacent region.Numerical results can be used for reference in the field of reducing multipath interference,radar object detection and identification,and remote sensing information processing.关键词
