Fast computation method for electromagnetic scattering characteristics of unmanned air vehicle

A new electromagnetic scatter modeling method of simulation with measurement date is presented in detail. Unmanned air vehicle(UAV) is tested in the anechoic chamber, inlet and tail nozzle special part scattering point is extracted; Simultaneity applied the high-frequency approximated method, reflection at conducting surfaces is computed by using physical optics approximation; diffraction at edges by using physical theory of diffraction, electromagnetic scattering characters of targets simulation combining with the measurement date is fast obtained. The calculated results are consistent with the result from measurement, which assure validity of the method, high effectivity and accuracy.
