REG: High-Speed Data Acquisition and Control Systems for Remote Sensing Applications

在NSF的支持下，PI在三个主要领域进行了广泛的研究：地球物理介质的毫米波遥感；粗糙表面的双基地散射；以及微波区森林冠层的建模。这三个领域都需要研究波与随机或非均匀自然介质的相互作用。主要目标是开发微波和毫米波遥感的基础信息。到目前为止，已经进行了广泛的实验和理论研究。在过去的10年里，PI开发了L、C、X和毫米波频段的移动车载雷达。然而，实验研究受到数据采集系统和控制器的速度和可靠性的限制。美国国家科学基金会工程研究设备资助项目中提供的快速数据采集系统和计算机将提高进行现场实验的能力，并开发波与地球物理介质相互作用的理论模型。

The PI has been conducting extensive research supported by NSF in three major areas: millimeter- wave remote sensing of geophysical media; bistatic scattering from rough surfaces; and modeling of forest canopy at the microwave region. All three areas require studying interaction of waves with random or inhomogeneous natural media. Major objectives are the development of basic information on microwave and millimeter-wave remote sensing. Thus far efforts have been directed to extensive experimental and theoretical investigations. Over the past 10 years, the PI has developed a mobile truck mounted radars at L, C, X, and millimeter-wave frequency bands. Experimental studies, however, have been limited by the speed and reliability of the data acquisition system and controllers. The fast data acquisition system and computers provided in this NSF Engineering Research Equipment Grant should advance the ability to conduct experiments in situ and to develop theoretical models of wave interactions with geophysical media.
