Wireless Communications and Detection Through Obscuring Environments

abstractecs - 0601394 y。该提案旨在利用我们最近对时间反转技术、相关成像技术和阵列相干层析成像技术的研究开发新技术。我们建议开发一个多传感器阵列网络系统，传输空间和时间调制信号。接收到的信号在空间和时间上进行相关和自适应，以获得高分辨率图像。由于介质的介入，信号会发生畸变，但我们利用我们最近在多散射随机介质相关成像和阵列层析成像技术方面的研究，以及我们最近在随机介质中的时间反转、成像、通信和超分辨率方面的研究，获得了更高的图像分辨率。本研究旨在发展时空极化波与复杂介质相互作用的广义理论，包括确定性和随机性。建议活动的智力价值：该提案涉及波与复杂环境相互作用理论的发展，分布式传感器的使用，以及包括空间，时间，频率和自适应系统在内的所有信息的统一处理。这种统一的方法在过去没有得到充分的探索，预计将导致成像和通信技术的重要进展。本研究的目标将是发展一门涵盖电磁波传播、通信、检测和信号处理的新学科。更广泛的影响建议活动带来的更广泛的影响：培训和教育学生是我们的优先事项之一。我们有一个本科微波实验室，我们聘请本科生和研究生进行微波测量实验和验证我们提出的研究。这将帮助学生理解整合实验、理论、统计考虑、传感器和信号处理的重要性。与学术界和工业界的其他研究人员合作也很重要，并将继续进行。

AbstractECS-0601394Y. Kuga, University of WashingtonThis proposal is directed to the development of new technologies making use of our recent study of time-reversal techniques, correlation imaging techniques, and array coherence tomographic imaging. We propose to develop an array network system of multiple sensors which transmit spatially and temporally modulated signals. The received signals are correlated and adapted in space and time in order to obtain high-resolution images. Signals are distorted due to the intervening medium, but we make use of our recent studies on correlation imaging through multiple scattering random media and array tomographic imaging technique to obtain improved image resolution, together with our recent studies on time-reversal, imaging, communication, and super-resolution in random media. This study is aimed at the development of generalized theories of space-time-polarization wave interactions with complex media, both deterministic and stochastic. Intellectual MeritIntellectual Merit of the Proposed Activity: This proposal addresses the development of theories of the interaction of waves with a complex environment, the use of distributed sensors, and the unified treatment of all information including space, time, frequency, and adaptive systems. This unified approach has not been fully explored in the past and is expected to lead to important advances in imaging and communication technologies. The goals of this study will be the development of a new discipline encompassing electromagnetic wave propagation, communication, detection, and signal processing. Broader ImpactsBroader Impacts Resulting From the Proposed Activity: The training and education of students is one of our priorities. We have an undergraduate microwave laboratory, and we employ undergraduate and graduate students for conducting experiments in microwave measurements and verification of our proposed studies. This will help students appreciate the importance of integrating experiment, theory, statistical considerations, sensors, and signal processing. Collaboration with other researchers in academia and industry is also important and it will be pursued.
