Abstract

High resolution imaging of objects in the Terahertz region of the electromagnetic spectrum requires operating in the near field region. Correlative interferometric approaches based on mathematical expressions for near field measurements are developed for reconstructing images of 1-D extended objects. The approach relies on providing constrained least squares fit between computed autocorrelation from sensor measurements and the expression for the near field autocorrelation.
近场阵列扩展目标的相关干涉成像
在电磁波谱的太赫兹区域对物体进行高分辨率成像需要在近场区域进行操作。提出了基于近场测量数学表达式的相关干涉测量方法,用于一维扩展目标图像的重建。该方法依赖于在传感器测量计算的自相关和近场自相关表达式之间提供约束的最小二乘拟合。
