Engineering Research Equipment Grant: Microwave and Millimeter Wave Scattering Measurement Systems

该工程研究设备补助金用于购买两台主要仪器，一台用于微波和毫米波实验的HP8510B矢量网络分析仪系统，以及一台用于微波和毫米波散射数值研究的MicroVax 3500计算机系统。 PI 一直在 NSF 的支持下在三个主要领域进行广泛的研究：随机非均匀介质中的成像；地球物理介质微波遥感； 以及地下物体散射和检测。 所有这些领域都需要研究波与随机或不均匀自然介质的相互作用。 主要目标是开发地球物理介质成像、遥感和检测的基本信息，包括水汽凝结、雾、冰雹、湍流空气、植被、土壤、岩石、雪和冰，其中多重散射和复杂物体的散射尤为重要。 这些努力是通过广泛的理论研究、数值研究和受控实验（包括光学和微波散射测量）来指导的。 所提出的微波和毫米波散射系统应实质性地提高其进行实验和数值研究以及开发波与地球物理介质相互作用的理论模型的能力。 它还将加强他们当前和未来在成像、遥感和探测方面的研究。

This Engineering Research Equipment Grant is for the acquisition of two major instruments, an HP8510B vector network analyzer system to be used for microwave and millimeter wave experiments, and a MicroVax 3500 computer system to be used for numerical studies of microwave and millimeter wave scattering. The PIs have been conducting extensive research supported by NSF in three major areas: imaging in random inhomogeneous media; microwave remote-sensing of geophysical media; and subsurface object scattering and detection. All of these areas require studies of the interactions of waves with random or inhomogeneous natural media. Major objectives are the development of basic information on imaging, remote-sensing, and detection in the geophysical media including hydrometeors, fog, hail, turbulent air, vegetation, soil, rock, snow, and ice where multiple scattering and scattering by complex objects are particularly important. The efforts have been directed by extensive theoretical investigations, numerical studies, and controlled experiments including optical and microwave scattering measurements. The proposed microwave and millimeter wave scattering systems should materially advance their ability to conduct the experiments and numerical studies and to develop theoretical models of wave interactions with geophysical media. It will also enhance their current and future research on imaging, remote-sensing, and detection.
