【摘要】 一般RCS测量只能获得被测物体固定某一单方位方向上的散射分布图,无法准确判断出目标强散射点的空间三维位置分布。首先,采用转台模式的近场二维微波成像,获取得到三维目标的二维投影成像分布;然后,再采用2个参考球做定位。在所成的图像中,依据定位球成像的位置准确判断出被测体目标强散射点所在的水平位置,从而通过投影关系计算出强散射点在被测体上的具体三维位置。通过实验验证,表明该技术可以高精度获得三维结构散射体的强散射点的三维位置信息。更多还原

【Abstract】 Generally the measurement of RCS can only get the scattered distribution of the measured object fixed on a single direction,and can not accurately judge the location of the three-dimensional space of the target intensity distribution scatterers.This paper firstly use the near field microwave imaging of two dimensional of the turntable mode,and acquire a two-dimensional projection imaging distribution of the three-dimensional object.Then two referenced balls are adopted to locate.In the formed image,the horizontal position of the target intensity distribution scatterers can be accurately judged based on the location of the image.Moreover the three-dimensional location of the target intensity distribution scatterers can be calculated by projection relations.The experiment proved that the technology can precisely achieve the three-dimensional location of the strong scattering points in the three-dimensional structure of scatterers.更多还原
