【Abstract】 When the horn dimension enclosed in radome is around λ , the 3-dimension ray tracking method is no longer valid . In this paper , the analysis on characteristics of small airborne radome is present , by means of aperture integration technique . It is found from the analysis results with the aperture-integration and surface-integration method that the gain of horn increases and the pattern undulates . The prediction has been proven by the experiment.更多还原
