Challenging Army-relevant communications and networking environments require novel methods and systems with sufficient robustness and resilience to enable operation in a covert fashion, especially in the presence of sophisticated adversaries. Recent studies suggest that regions of electromagnetic spectrum, such as deep ultraviolet (UV) spectrum, that are not being utilized in existing systems can provide unique advantages, particularly for more-covert short- range operations. However, the UV channel is not well understood, and techniques for the effective and efficient use of this channel for networking, such as spatial multiplexing, are still being investigated. In this paper, we report on experiments that validate previously hypothesized channel modeling behaviors, where we isolate and accurately measure the line-of-sight (LOS), single-scattering, and multiple-scattering components of measured returns and compare the measurements with theory. These experimental measurements exhibit good agreement with theoretical predictions, and demonstrate, in particular, predicted variations from ideal behavior in the multiple-scattering case. The validated behaviors play a key role in a previously proposed UV networking optimization framework. As such, we conclude this paper with additional development and examples of that framework in order to demonstrate the utility of the validated channel modeling.
