Title of Plenary: Fostering and transitioning military research – Lessons learned
Abstract: The operational and academic research domains have different goals, priorities and organizational cultures. While the first requires practical results that improve operational effectiveness, the second is characterized by detailed studies of complex problems, in which the associated schedules and results are not always easily translated to solving operational problems. However, performing such translation is a non-negotiable condition for obtaining doctrinal and technological independence of any nation. This talk explores success stories in the transition from basic research to the theater of operations, focusing in a model used by the US Department of Defense (DoD), while exploring possibilities within the national context.

Title of Lecture: The unique capabilities of low-frequency UWB SAR for remote sensing and surveillance applications
Abstract: Since late 1985, there has been ongoing development of Ultra Wide Band (UWB) Synthetic Aperture Radar (SAR) technology in Sweden. The idea to use UWB SAR, from the beginning, was to reduce the speckle noise in SAR images and by that get a perfect situation for target detection. It has been experimentally verificated that the speckle noise is low in UWB SAR. To reduce bandwidths and data rates the first airplane mounted UWB SAR system was operating at VHF, which is a very uncommon band for high-resolution radar systems. However, the operating frequency turned out to be a success when it comes to foliage penetration, and the combination of low frequency and UWB SAR has shown to have the ability to detect camouflaged and concealed targets. Particular by change detection between different illuminations low-frequency UWB SAR has indicated that it can detect human activity even in very dense forest environments. In this presentation, we will look into the technique of UWB SAR and compare it to traditional SAR. Mainly we will focus on the scattering properties and statistics, UWB SAR image processing, change detection, and even processing of moving targets.

Title of Lecture: Research in cybersecurity and C2 – Partnership possibilities
Abstract: This lecture addresses some of the major research projects in the areas of cybersecurity and command and control currently taking place at the C4I & Cyber Center (George Mason University – USA), the first and only center of this nature within an American civilian university. Current projects and concepts will be addressed in both areas, exploring possibilities for collaboration with national researchers.

Title of Lecture: Optical links exploiting Power Over Fiber and Raman Amplification for Sensor control – Application to cabled observatories for hostile or constraint environments
Abstract: This paper reviews our recent developments in Power over Fiber (PoF) for cabled observatories. This technology has been studied for long links up to 10 km more especially for submarine environments. The PoF system is based on an optical architecture in which power and data propagate simultaneously on the same single-mode fiber. The Raman scattering effect is exploited to amplify the optical data signals and leads to the minimization of the power consumption of the sensor node. In this presentation, we will first present the architecture developed and the experimental characterizations of such an optical link. Then we will expose its use for acoustic applications in submarine environments.

Title of Lecture: Optical functions for microwave signal processing using SOA and SOA-MZI
Abstract: This paper reviews our recent developments in microwave photonic functions based on Semiconductor Optical Amplifiers (SOAs) and SOA Mach–Zehnder interferometer structures (SOA-MZI). These devices present the ability to perform several processing functions for RF signals in the optical domain. The principle and the specifications of phase shifting, mixing and sampling are described.

Title of Lecture: An overview of solid rocket propulsion
Abstract: Purpose of this lecture is to offer a general survey of the current status of solid rocket propulsion in the general frame of modern propulsion devices. Being the oldest among the many techniques available, solid rocket propulsion represents a mature technology much used for a variety of civil and military applications. Thanks to specific features such as large thrust density, use readiness, long time storability, and simplicity of operations, it still is and will remain for decades a most successful approach. Despite their limited gravimetric specific impulse and modest real-time performance control, solid rocket motors offer prompt and storable large thrust in a compact, simple, and low-cost unit for very extended life times. Some promising ways to increase the gravimetric specific impulse by means of innovative energetic materials are discussed.
