摘要
多天线组合孔径是机载综合天线孔径的一种常见形式,散射机理复杂,隐身设计的难度较大,其散射分析与RCS减缩措施对实际工程应用有较大的意义。对多天线组合孔径的典型散射机理(包括镜面反射、两面角散射、腔体散射及棱边绕射等)作了简要分析,在此基础上提出了相应的隐身(RCS减缩)措施,并通过仿真及试验进行了验证。
The assembled aperture of multiple antennas is a familiar integrated aperture on airborne platform. Owing to the complicated scattering mechanism,stealth design of the assembled aperture is a difficult issue,therefore scattering analysis and RCS reduction is significant for practical engineering application. The typical scattering mechanisms of the assembled aperture of multiple antennas are analyzed briefly,including mirror reflection scattering,dihedral scattering,cavity scattering,edge scattering and so on. On this base,the corresponding stealth（ RCS reduction） methods are proposed and validated by simulation and experiment.
