海背景下箔条云电磁散射研究
Electromagnetic scattering simulation from a chaff cloud above the ocean
摘要
Abstract
Chaff can generate pseudo-targets at radar receivers,interfering with the detection and tracking of real targets.This paper proposes an electromagnetic(EM)scattering simulation model to address the scattering characteristics of chaff clouds in a low-altitude ocean environment.The study analyzes the influence of coupling effects between the chaff cloud and the sea surface on EM scattering.To account for multiple scattering effects comprehensively,the four-path theory is employed to model interactions between the chaff cloud and the sea surface.For regions with high-density chaff clouds,the vector radiative transfer method is applied to simulate energy redistribution and internal coupling effects within the cloud.Furthermore,an advanced integral equation model is utilized to accurately compute the EM scattering contributions of the sea surface under various sea conditions.Numerical methods are used to validate the accuracy of the simulation results.Additionally,the paper examines the scattering behavior of chaff clouds above the sea surface across a range of scenarios.关键词
