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。
The Rayleigh composite electromagnetic scattering characteristics of a pair of media spherical targets were studied in C-band, and the analytic formula of the target composite scattering cross section was obtained, which verified the correctness of the results obtained. The polarization state of the incident wave, the target distance, the target size, The results show that the influence of adjacent targets on the target scattering has the characteristics of dipole radiation. The composite scattering cross section of the main target is a function of the size, dielectric constant and location of the adjacent targets The results laid the theoretical foundation for the accurate measurement of the target scattering cross section and the electromagnetic interaction.
