摘要: 該文提出一種計(jì)算復(fù)雜目標(biāo)高頻RCS的像素法,論述了像素法的特點(diǎn)以及與GRECO方法的不同點(diǎn)。該文還提出一種新的曲面像素法,并給出各種不同像素法計(jì)算高頻目標(biāo)RCS結(jié)果的比較分析,證實(shí)曲面像素法在提高目標(biāo)的RCS特性分析計(jì)算精度方面的突出優(yōu)點(diǎn)。文中還給出運(yùn)用曲面像素法計(jì)算多種復(fù)雜目標(biāo)體的分析實(shí)例。

Abstract: A new method for computing high-frequency RCS of objects with complex configuration, called. Curved Surface Pixel (CSP) method, is presented in this paper. The distinction between CSP method and GRECO method is described. Several different approaches of the pixel methods are analyzed. Many computation examples for spheroid, ellipsoid, cone, missile mode and aircraft mode show that the CSP method has advanced computation accuracy. -
