We have developed an interferometric synthetic aperture incoherent imaging system at 94 GHz, in which a high-power electronic millimeter wave source (Gunn Oscillator) is integrated with a continuous-wave terahertz (THz) photomixing detection system to achieve a high signal-to-noise ratio. Imaging of a point source located 10?m away from the detector array is presented. Two-dimensional THz reflective images of an extended object with different shapes are reconstructed with only four detectors by use of rotational synthesis.
我们开发了一种94吉赫兹的干涉合成孔径非相干成像系统,其中一个高功率电子毫米波源(耿氏振荡器)与一个连续波太赫兹(THz)光混频检测系统集成在一起,以实现高信噪比。展示了对一个位于距探测器阵列10米处的点源的成像。通过旋转合成,仅用四个探测器就重建了具有不同形状的扩展物体的二维太赫兹反射图像。
