Abstract
This paper addresses the issue of how to characterize an antenna's performance in a SAR system-particularly in ultra-wide-bandwidth and/or ultra-wide angle (UWB/A) SAR-based on simple gain-magnitude versus frequency and angle measurements provided in data sheets. We present eight measures of merit. As illustrative examples, we compare an ideal mathematical model to measurements of an actual antenna designed to perform UWB/A SAR over up to 65-degree integration angles and over a 150- to 550-MHz frequency band.
本文解决了如何根据数据表中提供的简单增益幅度与频率和角度的测量来表征SAR系统中天线性能的问题，特别是在超宽带和/或超广角(UWB/ a) SAR中。我们提出了八个衡量优点的标准。作为示例，我们将理想的数学模型与实际天线的测量结果进行了比较，该天线设计用于在高达65度的集成角和150至550 mhz的频段上执行UWB/A SAR。
