CAREER: An Integrated Research/Educational Plan to Develop and Deploy a Pointable, Hyperspectral Remote Sensing Instrument on a Tethered Balloon

职业生涯：一项综合研究和教育计划，目的是在系留气球上开发和部署一个有针对性的高光谱遥感仪器卫星和机载遥感仪器拍摄的地球图像提供了一个非常有价值但又有限的视角。虽然遥感技术使地球系统的研究发生了革命性的变化，能够快速和频繁地对大片表面积进行成像，但各种限制可能会限制遥感数据的空间分辨率(即像素大小)，以至于观测到的地表细节不足以研究关键的环境过程。因此，通常需要复杂的数学程序来得出各种地面覆盖类型(如树木、草地、裸露土壤和水)的“亚像素”分数。为了补充和验证这些数学程序，需要新的遥感技术来弥合小规模地面观测与更大规模的飞机和卫星测量之间的差距。将开发一种仪器，它可以连接到大型无人飞艇的系绳上，并可以升降以从一系列中间视角观察地球。南达科他州矿业与技术学院(SDSM&Amp；T)的一个综合研究/教育项目将开发和部署一种轻型、最先进的遥感仪器包，用于这种系留气球平台。大气科学研究所的研究生和教职员工将与本科生一起参加SDSM&&T；先进制造和生产卓越中心(CAMP)和高级设计课程，以设计、建造和测试仪器。此外，该仪器将被用来开发一个遥感教育模块，以整合到SDSM&&T印第安人学习和领导科学知识(SKILL)暑期项目中，供美国原住民预科学生使用。仪器的开发将在五年开发期间的每个学年逐步进行。在完成仪器开发的每个阶段后，研究生和首席研究员将使用该仪器进行由气球平台实现的几个遥感实验。例如，气球平台将被用来研究如何验证和改进使用各种数学“光谱混合分析”技术的亚像素景观分量的覆盖估计。到项目结束时，高光谱仪器平台将能够稳定飞行，实时仪器对地数据传输，并将从地面远程指向。这项工作的主要目标是1)促进学生科学家和工程师之间的合作，2)利用这种合作的成果进行新的研究并在地球遥感方面取得进展，3)使这项技术和研究为少数族裔学生所熟悉，并鼓励他们从事科学和技术事业。

CAREER: An Integrated Research and Education Plan to Develop and Deploy a Pointable, Hyperspectral Remote Sensing Instrument on a Tethered BalloonImages of the earth taken by satellite and aircraft-based remote sensing instruments offer an immensely valuable, yet limited perspective. While remote sensing technologies have revolutionized the study of the earth system by enabling large surface areas to be imaged quickly and frequently, various limitations can restrict the spatial resolution (i.e. pixel size) of remote sensing data to the point where observable surface detail is insufficient to study critical environmental processes. As a result, complex mathematical procedures are often necessary to derive "sub-pixel" fractions of various ground cover types such as trees, grasses, bare soil, and water. To complement and validate these mathematical procedures, novel remote sensing techniques are needed to bridge the gap between small-scale, ground-based observations and larger scale aircraft- and satellite-based measurements. A instrument will be developed that can be attached to the tether line of a large, unmanned blimp and raised and lowered to view the earth across a range of intermediate perspectives. An integrated research/education program at the South Dakota School of Mines and Technology (SDSM&T) will develop and deploy a lightweight, state-of-the-art remote sensing instrument package for use on such a tethered balloon platform. Graduate students and faculty in the Institute of Atmospheric Sciences will team with undergraduate engineering students participating in the SDSM&T Center of Excellence for Advanced Manufacturing and Production (CAMP) and Senior Design Courses to design, construct, and test the instrument. In addition, the instrument will be used to develop a remote sensing educational module for integration into the SDSM&T Scientific Knowledge for Indian Learning and Leadership (SKILL) summer program for pre-college Native American students. Instrument development will occur incrementally during each academic year of the five-year development period. Upon the completion of each stage of instrument development, graduate students and the Principal Investigator will use the instrument to conduct several remote sensing experiments made possible by the balloon platform. For example, the balloon platform will be used to investigate how cover estimates of sub-pixel landscape components using various mathematical "spectral mixture analysis" techniques can be validated and improved. By the end of the project, the hyperspectral instrument platform will be capable of stable flight, real-time instrument-to-ground data transmission, and will be remotely pointable from the ground. The overarching goals of this work are 1) to foster collaboration between student scientists and engineers, 2) to utilize the results of this collaboration in order to conduct novel research and make advances in terrestrial remote sensing, and 3) to make this technology and research familiar to minority students and encourage them to pursue careers in science and technology.
