Engineering Research Equipment Grant: Microwave Network Analyzer/Dynamic Signal Analyzer for Radar Clutter Decorrelation Studies

这项工程研究设备补助金将使人们能够进行实地实验，研究来自不同地形目标的雷达反射信号的去相关特性。该系统由配置为近程雷达系统的便携式微波网络分析仪和用于基带信号处理和分析的动态信号分析仪组成。时间和/或空间去相关数据将在不同的频率、极化、入射角和天线波束宽度下，在不同的地面真实条件下收集。还将开发简单的模型，以便根据测量的地面真实参数预测去相关时间/距离，并与测量数据进行比较。预计这项研究将对军事和商业应用中的目标识别和地形分类产生影响。

This Engineering Research Equipment Grant will enable field experiments to be performed for studying the decorrelation characteristics of radar reflected signals from various terrain targets. The proposed system consists of a portable microwave network analyzer configured as a short-range radar system, and a dynamic signal analyzer for baseband signal processing and analysis. The temporal and/or spatial decorrelation data will be gathered at various frequencies, polarizations, incidence angles, and antenna beamwidths, under varied ground-truth conditions. Simple models will also be developed in order to predict the decorrelation time/distance based on measured ground-truth parameters, and compared to measured data. The research is expected to have an impact on target identification and terrain classification for both military and commercial applications.
