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

本工程研究设备拨款用于购置两台主要仪器，一台HP8510B矢量网络分析仪系统，用于微波和毫米波实验，以及一台MicroVax 3500计算机系统，用于微波和毫米波散射的数值研究。在NSF的支持下，pi在三个主要领域进行了广泛的研究：随机非均匀介质成像；地球物理介质微波遥感；以及地下物体的散射和探测。所有这些领域都需要研究波与随机或非均匀自然介质的相互作用。主要目标是发展地球物理介质成像、遥感和探测的基本信息，包括水成物、雾、冰雹、湍流空气、植被、土壤、岩石、雪和冰，在这些介质中，多重散射和复杂物体的散射尤为重要。广泛的理论研究、数值研究和包括光学和微波散射测量在内的控制实验指导了这些工作。所提出的微波和毫米波散射系统应大大提高其进行实验和数值研究的能力，并建立波与地球物理介质相互作用的理论模型。它还将加强他们目前和未来在成像、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.
