【摘要】 小型化测试仪以H面扇形喇叭探头作为传感器,用小型矢量反射计作为指示器。随着口径增大,相位差逐渐减小。当口径足够大时,口径处的场可看作平面波结构。故只要合理选择喇叭天线尺寸,则口径处的输出场可近似为雷达发射的平面波,近场测得的吸波材料雷达波反射率可等效为雷达的远场探测结果。更多还原

【Abstract】 The miniaturization apparatus takes H-plane fan-shaped horn antenna as sensor, little vector reflector as indicator. When the caliber become larger and larger, the filed phase difference was become less and less. When the aperture of the horn was large enough, the output field could be seen as plane wave. So if only the horn size was reasonable, the output field of the horn was similar to the field eradiated by the radar, then radar absorbing material‘s reflection could be obtained by the horn that was equivalent to the result gotten by radar更多还原
