摘要
在C波段研究了一对介质球体目标的瑞利复合电磁散射特性,得到了目标复合散射截面解析式,验证了所得结果的正确性;研究了入射波极化状态、目标距离、目标大小、介电常数等因素对复合散射截面的影响,结果表明,邻近目标对本目标散射的影响具有偶极辐射的特点,主目标的复合散射截面是邻近目标的大小、介电常数及其位置等因素的函数;结果为目标散射截面的准确测量、电磁相互作用等奠定了理论基础。
In C wave band, the Rayleigh complex scattering property of a pair of spheres is researched. The complex scattering cross section is presented and its validity is tested. The effects on the scattering property induced by the polarization of the incident wave, target distance, target size and its dielectric constant are developed. Results show that the influence produced by the surrounding targets on the scattering of the primary target has the characteristics of dipole radiation. This Rayleigh scattering is function of the neighbor target size, its dielectric constant and its azimuth. The results offer a base for correct measuring of RCS and the study of electromagnetic interaction.
