Rapid Simulation of Electromagnetic Scattering Characteristics of Chaff Clouds Under Monostatic and Bistatic Detection
摘要
Abstract
A modeling method that integrates an aerodynamic motion model with an electromagnetic scattering model is presented.This method is used to profoundly analyze the electromagnetic scattering properties of chaff clouds in intri-cate electromagnetic environments.By examining the force characteristics of chaff strips,a six-degree-of-freedom mo-tion model is established,taking into account gravity,air resistance,and spin torque.In the context of electromagnetic scattering,a high-precision analytical model for the polarimetric scattering field of a single chaff dipole is derived through rigorous electromagnetic theory and cross-validated with the method of moments(MoM).Building upon this,a multi-orientation chaff-cloud electromagnetic scattering model is developed that enables rapid and efficient large-scale simulations for both monostatic and bistatic detection scenarios.Furthermore,by simulating the diffusion motion state of the chaff cloud at different times,the Doppler effect of chaff clouds is researched by simulating their diffusion motion states at various time-periods,the influence of wind speed on the spectral broadening of chaff clouds is analyzed.Re-sults indicate that the root mean square error of the simulation accuracy of the proposed model is less than 2.95 dB,sig-nificantly lower than that of traditional methods,and its simulation speed is far superior to that of numerical methods.The research provides an electromagnetic scattering theory foundation and target-characteristic data support for assess-ing chaff-jamming effectiveness and optimizing anti-jamming strategies.关键词
