| 摘 要： | 在220～330 GHz频段，采取自由空间场形式，采用扫频连续波信号进行目标雷达散射截面(RCS)测量。系统由矢量网络分析仪，毫米波混频器，馈源及目标支撑系统组成。多种散射测量技术将通过实验验证并应用于目标测量中。最终保证系统对–23.6 dBsm目标的测量精度达到±3 dB。

| Abstract: | The measurement system has been built with Stepped Frequency Continuous Wave (SFCW) signal for Radar Cross Section (RCS) measurements in free-space at 220～330 GHz. The system consists of vector network analyzer, Millimeter-Wave Converters and target support structure. The measurement techniques which are used in scattering measurements are verified by RCS measurement data. The system measurement accuracy is control within about ±3 dB at –23.6 dBsm. |
