基于微波倍频源太赫兹频段雷达散射截面测量
|
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 d Bsm目标的测量精度达到±3 d B。
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 d B at –23.6 d Bsm.
