在本文中，超宽带（UWB）传感器阵列的能力，层析雷达的电大目标。当成像扩展到真实的对象时，主要关注的是实现对象形状及其电特性的正确重建。提出了一种基于超宽带双聚焦算子（UWB-BF）的具有良好层析成像能力的通用框架。这种通用方法提供了对传感几何形状和图像质量参数的基本权衡的全面理解。通过数值模拟和测量适用于规范以及复杂的对象，基本的设计标准进行评估和UWB断层雷达成像的潜力。
In this paper, the capability of ultra-wide-band (UWB) sensor arrays for tomographic radar of electrically large objects is presented. The major concern when imaging is extended to real objects is to achieve a correct reconstruction of the object shape and its electric properties. A general framework based on a UWB bifocusing operator (UWB-BF) with good tomographic imaging capabilities is presented. This general approach provides a comprehensive understanding of the basic tradeoffs with regard to sensing geometry and image quality parameters. Through numerical simulations and measurements applied to canonical as well as to complex objects, basic design criteria are assessed and the potential of UWB tomographic radar imaging is presented.
