基于太赫兹雷达阴影特性的目标结构推断技术
Target structure inference technology based on terahertz radar shadow characteristics
摘要
Abstract
Terahertz radar,with its high-resolution imaging capability,renders shadows in Synthetic Aperture Radar(SAR)images with high clarity and rich detail,offering a new dimension for target structure inference.This paper systematically explores the shadow characteristics of terahertz radar and their application value in structure inversion.Through imaging experiments on typical targets such as tall towers,moving tanks,trees,and sundials,three major advantages are validated:shadow imaging effectively eliminates the layover effect in tall buildings,providing unambiguous geometric contours;shadows of moving targets present stable,optically similar outlines,offering a new approach for judging the structure of moving objects;and shadows reliably reveal extended fine structures such as tank barrels and gnomon.The research demonstrates that the shadow characteristics of terahertz radar can effectively compensate for the shortcomings of traditional scattering intensity-based methods,providing a highly reliable technical approach for target structure inference.关键词
