标题： Frequency-responsive RCS characteristics and scaling implications for ISAC development

摘要： 本文研究了各种目标的雷达截面（RCS），旨在分析RCS特性如何随频率变化。 如自动引导车（AGV）、行人和全尺寸汽车等目标在行业标准中称为FR2和FR3的频段内进行了测量。 在多种环境中进行了测量，包括室内和室外，以确保全面的情景覆盖。 采用的RCS提取方法进行背景减法，然后进行时域门控以隔离目标的影响。 此分析比较了RCS值以及最大贡献点在不同频段中的分布情况，基于RCS的距离响应。 结果分析表明RCS值如何随频率和目标形状变化，提供了这些目标电磁行为的见解。 关键发现强调了基于频率和几何形状对RCS值进行缩放的复杂性，并且在不同类型的材料和形状之间有所不同。 这些见解对于推进感知系统和增强3GPP信道模型至关重要，特别是针对6G标准提出的集成感知与通信（ISAC）技术。 显示英文摘要

摘要： This paper presents an investigation on the Radar Cross-Section (RCS) of various targets, with the objective of analysing how RCS properties vary with frequency. Targets such as an Automated Guided Vehicle (AGV), a pedestrian, and a full-scale car were measured in the frequency bands referred to in industry standards as FR2 and FR3. Measurements were taken in diverse environments, indoors and outdoors, to ensure comprehensive scenario coverage. The methodology employed in RCS extraction performs background subtraction, followed by time-domain gating to isolate the influence of the target. This analysis compares the RCS values and how the points of greatest contribution are distributed across different bands based on the range response of the RCS. Analysis of the results demonstrated how RCS values change with frequency and target shape, providing insights into the electromagnetic behaviour of these targets. Key findings highlight how much scaling RCS values based on frequency and geometry is complex and varies among different types of materials and shapes. These insights are instrumental for advancing sensing systems and enhancing 3GPP channel models, particularly for Integrated Sensing and Communications (ISAC) techniques proposed for 6G standards.
