Cognitive Radio : A Solution for Issues in Network Convergence

While planning for strategic communication no nation or organisation can ignore the problems of dynamic radio resource allocation and interference. Among lot number of technologies as a solution Cognitive Radio (CR) is the best one, which helps to overcome the problem of interference, and also allow efficient and dynamic radio resource allocation. Applying Cognitive Radio Networks (CRN) to strategic communications as a solution, this roadmap has been proposed by nations and organizations. For fast network deployment it is mandatory to overcome traffic problem in spectrum, increase communication reshaping mechanism and also strategic radio should act as multi-functional Radio-Frequency(RF) Unit, these are the themes for which CRN is the choice. Wireless Sensor Networks(WSNs) present day have many challenges, if it get clubbed with CR, many problems can be solved. Theme of our research is to empower CRN, so that it will help to solve above problems and also help to manage traffic in network convergence services without ignoring or compromising security

Introduction to Drone Detection Radar with Emphasis on Automatic Target Recognition (ATR) technology

This paper discusses the challenges of detecting and categorizing small drones with radar automatic target recognition (ATR) technology. The authors suggest integrating ATR capabilities into drone detection radar systems to improve performance and manage emerging threats. The study focuses primarily on drones in Group 1 and 2. The paper highlights the need to consider kinetic features and signal signatures, such as micro-Doppler, in ATR techniques to efficiently recognize small drones. The authors also present a comprehensive drone detection radar system design that balances detection and tracking requirements, incorporating parameter adjustment based on scattering region theory. They offer an example of a performance improvement achieved using feedback and situational awareness mechanisms with the integrated ATR capabilities. Furthermore, the paper examines challenges related to one-way attack drones and explores the potential of cognitive radar as a solution. The integration of ATR capabilities transforms a 3D radar system into a 4D radar system, resulting in improved drone detection performance. These advancements are useful in military, civilian, and commercial applications, and ongoing research and development efforts are essential to keep radar systems effective and ready to detect, track, and respond to emerging threats.Comment: 17 pages, 14 figures, submitted to a journal and being under revie

Commercialization Analysis of SBIR Funded Technologies

The United States Small Business Innovation Research (SBIR) Program invests $2.2 billion annually into domestic innovation stimulation. The Department of Defense (DoD) contributes almost$1 billion of that investment; of which the Air Force accounts for 25%. Commercialization, either the transfer to programs of record or further industrial investment, is the program’s objective. Data from this research indicates that Air Force programs have a 7.6% commercialization rate; representing an opportunity to improve. Leveraging best practices from industry; this research provides a method to align investments with needed capabilities. This method exploits established user need taxonomies, the DoD Joint Capability Area (JCA) listing and the National Aeronautics and Space Administration’s SBIR taxonomy, to categorize SBIR efforts. This categorization allows for needs based innovation portfolio management. Metrics are developed that identify several technologies of interest that over perform and underperform relative to the overall portfolio. This development of metrics and visualization tools provides managers a new means to control and improve their innovation investments. This needs based mapping facilitates sharing and coordination amongst aerospace SBIR stakeholders. This thesis concludes by recommending improvements to the existing JCAs, the SBIR topic development process and the establishment of an aerospace SBIR community of interest
