Simulation And Experiment Study On EM Scattering From Targets Coating With Magnetic Absorbing Material

With the development of dock technique and consciousness of public's self-protection is gathering strength, radar absorbing material is applied more and more widely in the military and civilfield.The function of radar absorbing material must be known about before it is applied.Reflection is the most important index for wave absorbing rate.For have good function of RAM,especially at the range of the frequency from 2G to 18G,the used material and technology is difficult to achieve the objective.So using new material and optimize structure is the key to improve the function of RAM.According to GJB2038-94,the method of RCS measurement in far-field condition is commondly,used to measure the radar absorber reflectivity.By using teching platform and sofewave of automated measurement systems,correct the testing system,manage the testing data, start the reseaech of Magnetic absorbing material.This method can improve the degree of combination between the simulation calculation and application by comparing simulation results with the measurement results. Thus the consistency between simulation results and measurement results of RCS with can be improved.
