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的是推进工程和科学社区的遥感技术的最新技术，以了解海冰的地球物理和热力学特征。研究将在三个领域进行：1）海冰遥感实验，用于检测海冰油中的油，2）海冰散射的电磁建模； 3）开发用于北极遥感的新测量平台。然而，我们对海冰地球物理学和热力学的快速变化如何影响卫星规模散射的知识仍然存在。随着北极运输的增加，由于冰条状况的减少而增加，这与海上石油勘探，钻探和生产的扩张计划相比，在这个脆弱的环境中，我们的漏油风险增加了。加拿大有责任确保我们有能力发现和减轻这种环境灾难的风险。需要在遥感中进行研究来发展对雷达波相互作用的基本理解并推进检测工具和方法。***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了解波浪相互作用的机制，并可用于开发用于检测被困在海冰下面的油的技术。从我的建模研究的结果中，我将设计，建造和测试遥感有效载荷，以集成到无人驾驶汽车（UAV）中，并与天线进行调查，这些天线用于检测特定参数，例如海冰中的油。技术和改进的海冰中油的方法。天线将进行模拟，建造，测试和集成到遥感应用的新型测量平台中。***在北极遥感领域的发现将有助于维持加拿大作为与北方可持续发展有关的技术，科学和经济问题研究领导者的地位。该研究计划基于工程学院与曼尼托巴大学地球观察科学中心（CEO）之间的合作研究，并得到了与行业的合作伙伴关系的支持。硬件研究将在电气和计算机工程部进行，而遥感研究将在Sea-Ice环境研究设施（SELF）和新的CFI资助的Churchill Marine天文台（CMO）进行。
