The main objective of my proposed research program is to advance the state-of-the-art in remote sensing technologies for the engineering and scientific communities to understand the geophysical and thermodynamic characteristics of sea ice. Research will be undertaken in three areas: 1) Sea Ice Remote Sensing Experiments for Detection of Oil in Sea Ice, 2) Electromagnetic Modeling of Sea Ice Scattering, and 3) Development of New Measurement Platforms for Arctic Remote Sensing.Satellite remote sensing has historically been used to monitor the Arctic; however, lingering uncertainties remain in our knowledge of how rapid changes in sea ice geophysics and thermodynamics affect the satellite-scale scattering. As transportation through the Arctic increases in response to reduced ice conditions, compounded by plans for expansion in offshore oil exploration, drilling, and production, we have an increased risk of an oil spill in this fragile environment. Canada has a responsibility to ensure that we are in a position to detect and mitigate the risk from such an environmental disaster. Research in remote sensing is required to develop the fundamental understanding of radar wave interactions and to advance detection tools and methods.In order to interpret radar data, I rely on electromagnetic models to describe how microwaves interact with the complex sea ice medium. New modeling methods will help me to understand the mechanisms of the wave interactions and can be used to develop techniques for detecting oil that is trapped underneath sea ice. From the results of my modeling studies, I will design, build, and test remote sensing payloads to be integrated onto unmanned aerial vehicles (UAVs) with antennas that are tuned for detection of specific parameters, such as oil in sea ice.The expected major research outputs of this program will be an enhanced understanding of how radar can be used to determine sea ice geophysical and thermodynamic state, development and validation of innovative electromagnetic modeling techniques, and improved methods for detection of oil in sea ice. Antennas will be simulated, built, tested, and integrated into novel measurement platforms for remote sensing applications.Discoveries in the areas of Arctic remote sensing will help maintain Canada's status as a leader of research in technological, scientific, and economic issues related to sustainable development in the north. This research program builds on a collaborative research effort between the Faculty of Engineering and the Centre for Earth Observation Science (CEOS) at the University of Manitoba, supported by partnerships with industry. Hardware research will be conducted in the Department of Electrical and Computer Engineering, while remote sensing research will be performed at the Sea-ice Environmental Research Facility (SERF) and at the new CFI-funded Churchill Marine Observatory (CMO).

我提出的研究计划的主要目标是推进国家的最先进的遥感技术的工程和科学界了解海冰的地球物理和热力学特征。研究将在三个方面进行：1）海冰遥感实验，以探测海冰中的石油，2）海冰散射的电磁模拟，3）北极遥感新测量平台的开发。然而，在我们对海冰物理学和热力学的迅速变化如何影响卫星尺度散射的认识方面，仍然存在着挥之不去的不确定性。随着通过北极的运输因冰况减少而增加，加上海上石油勘探、钻井和生产的扩大计划，我们在这个脆弱的环境中发生石油泄漏的风险增加。加拿大有责任确保我们能够发现和减轻这种环境灾难的风险。遥感研究需要发展雷达波相互作用的基本理解和先进的检测工具和方法。为了解释雷达数据，我依靠电磁模型来描述微波如何与复杂的海冰介质相互作用。新的建模方法将帮助我理解波浪相互作用的机制，并可用于开发探测海冰下石油的技术。根据我的建模研究结果，我将设计、建造和测试遥感有效载荷，这些遥感有效载荷将被集成到带有天线的无人机（UAV）上，这些天线被调整用于检测特定参数，如海冰中的石油。该计划的预期主要研究成果将是加深对雷达如何用于确定海冰的地球物理和热力学状态的理解，开发和验证创新的电磁建模技术，改进海冰中石油的探测方法。北极卫星将被模拟、建造、测试并集成到新的遥感应用测量平台中。北极遥感领域的发现将有助于保持加拿大在与北方可持续发展有关的技术、科学和经济问题研究方面的领先地位。该研究计划建立在工程学院和马尼托巴大学地球观测科学中心（CEOS）之间的合作研究工作的基础上，并得到了与工业界合作伙伴关系的支持。硬件研究将在电气和计算机工程系进行，而遥感研究将在海冰环境研究设施（SERF）和由国际合作基金会资助的新的丘吉尔海洋观测站（CMO）进行。
