摘要/Abstract

摘要：

针对实际工程中材料宽频段反射特性频域测量面临的问题,提出一种基于时域法的自由空间超宽带反射特性快速测量方法。通过时域测量系统搭建、基于“时间窗”脉冲信号的提取方法分析、反射系数计算等内容,对系统优势进行了综合分析,形成了实际测量方案。测量结果表明,这种方案具有测量环境要求低、测量速度快、方便准确等优势,一次测量可以得到常见雷达频段(2~18 GHz)板状材料的反射系数。

关键词: 时域法, 窄脉冲, 反射系数, 超宽带, 快速测试

Abstract:

In order to solve the problems faced in the frequency domain measurement of the broadband reflection characteristics of materials in practical engineering,this paper proposes a fast test scheme for free-space ultra wideband reflection characteristics based on the time domain method.Through the construction of the time domain measurement system,the analysis of the extraction method of the pulse signal based on the "time window",the calculation of the reflection coefficient,etc.,the system advantages are comprehensively analyzed,and the actual measurement plan is formed.Measured results show that the scheme has the advantages of low measurement environment requirements,fast measurement speed,great convenience and high accuracy,and that the reflection coefficient of plate-like materials in the common radar band (2~18 GHz) can be obtained by one measurement.

Key words: time domain method, narrow pulse, reflection coefficient, ultra wideband, fast measurement
