Microwave imaging by scattering

  • 摘要: 提出了一种适用于隐匿武器探测、打击走私以及公共场合安检的微波成像探测方法.该方法要求雷达在一个二维平面上扫描,即合成一个平面孔径,通过对雷达接收回波数据的合成孔径处理可以提高雷达的成像分辨率以及对目标的探测能力.雷达可以工作在准单站模式下且只需以单色波照射目标,利用接收到的目标的散射回波的相位和幅度信息重构出目标的二维像.提出了一种适用于近场条件下二维图像的重构算法,并对算法做了详细推导,利用该算法对模拟和实测数据进行了处理.结果表明该算法具有良好的空间分辨率和辐射分辨率,以及在不进行三维成像的条件下可以实现距离向目标的探测.
