Multispectral Drone Detection System

This video describes a paper I co-authored and was published by the IEEE Access journal with the title: “Systems Engineering Baseline Concept Of A MultiSpectral Drone Detection Solution For Airports.” The paper is open access and can be downloaded from the IEEE Xplore Digital Library.

Abstract:The baseline concept for a Multi-Spectral Drone Detection (MSDD) system for use in airports is generated. The baseline development process is based on a modified System of Systems Architecting with Ilities (SAI) method. The solution uses multiple independent sensors and when the sensor outputs are combined, they provide functionality the individual systems were never intended to provide. Also, several of sensors are pre-existing and have their own funding, operations, and management. The problem of drone detection is described and examples are given which justify the need for the system. Then the specific need for airport protection is described. The result is a feasible baseline design that is capable of meeting the need.


Terabit Per Second Satellite Systems Using Elliptic Orbit Satellites

This video describes a paper I co-authored and was published by the IEEE Access Journal with the title: “Systems Engineering of a Terabit Elliptic Orbit Satellite and Phased Array Ground Station for IoT Connectivity and Consumer Internet Access.” The paper is open access and can be downloaded from the IEEE Xplore Digital Library.

Abstract: Systems engineering of a satellite based data communication baseline concept is presented to achieve terabit per second throughput. It uses a constellation of 5 Molniya satellites and one dimension electronic scanning phased array ground terminals. The result is a baseline concept that meets customer needs for internet of things (IoT) data connectivity and for consumer high data rate internet access. Molniya orbit satellites provide the benefits of available bandwidth, lack of interference with other satellite links, and less crowded orbital paths. A drawback is that they are not geostationary since they have highly elliptical orbits. This requires ground station terminals with the ability track the satellites as they pass overhead during their orbit. However, since Molniya satellites with a properly selected eccentricity pass along the same path at nearly constant elevations relative to a fixed position on the Earth, simple and low cost single axis scanning antennas can be used for the consumer ground terminal. This is a distinct advantage compared to competing low earth orbit (LEO) constellations. The proposed solution leverages advances in semiconductor technology and low cost antenna laminate substrate materials for an affordable phased array tracking ground terminal antenna. This work presents link budget trade studies, system concept, orbital dynamics simulation results, and ground station component trade study.


Transmit Receive Modules Book

This video describes the book I co-authored with the title Transmit Receive Modules for Radar and Communication Systems.

Description: The use of electronically scanned phased arrays is increasing in systems such as radar, wireless networks, and satellite ground terminals. An important and necessary component for these systems is the transmit receive (T/R) module, which provides the amplification and electronic beam steering that is required for proper function. This new resource presents a comprehensive overview of all design, fabrication, integration, and implementation issues associated with T/R modules for radar and communications.
This book provides engineers and researchers with practical designs and 44 examples of analysis, circuits, and components used in T/R modules. It also provides a solid explanation of the theory for how T/R modules operate and how they can be optimized. In addition, this book shows how the latest technical advances in silicon germanium (SiGe) and gallium nitride (GaN) are allowing levels of performance that were previously unachievable. The book concludes with informative chapters on testing, cost considerations, and the future of next generation T/R modules.


Four Reasons You Need To Know About Phased Arrays

This video describes why phased arrays will be used in many new systems.

Description: Phased arrays have been traditionally used in military systems such as fighter plane radar. However, they are being deployed or considered for deployment in a variety of new application such as mobile phones, 5G networks, satellite systems, and internet of things (IoT) solutions. This video explains how phased arrays are being considered for deployment. The video was produced by MPT, Inc. which is a company founded by Rick Sturdivant.
