ALERT REUs Present Summer Research
This summer, ALERT hosted three undergraduate students at Northeastern University to participate in a 10-week Research Experience for Undergraduates program. The ALERT REU program at NEU is partnered with other REU programs in the university’s College of Engineering, and builds a cohort of motivated students who attend professional development meetings and program activities, including presentations on Research Ethics, Lab Safety, PowerPoint Presentation Skills and Scientific Storytelling. At the end of the summer, each REU gives a final presentation of their research project. The presentation addresses the project’s overall mission and endeavors, the REU’s specific contributions to the project, as well as what knowledge and skills they gained through the process. This year’s students worked on projects related to ALERT’s Bulk Sensors & Sensor Systems research.
REU Anthony Bisulco (’18) is a third year NU student who worked with Professor Jose Martinez-Lorenzo on ALERT’s Rapid Security Threat Detection via MIMO (Multiple Input, Multiple Output) Millimeter Wave Imaging project.
In his words, “The main purpose of my REU project is to improve the overall passenger experience during the airport security screening process. Currently, this process is plaqued with many downfalls such as slow throughput, frequent false alarms and significant passenger divestment and recollection. The working goal of the project I am working on is to improve this process by creating ‘On the Move Screening’ where passengers walk at a normal pace through what appears to be a tunnel without the need to divest any clothing or personal items.”
Anthony’s project worked to increase the image quality of a 3D imaging millimeter wave radar (“Tunnel System”) with the goal of improving the system’s threat detection capability. “One part of this radar is various transmitters/receivers which illuminate/receiver the target (Human Torso) at various angles. As a result of adding transmitters/receivers the image quality is increased. Rather than adding multiple transmitters or receivers, my project added microwave switches to the system, which is the equivalent of adding more transmitters and receivers for imaging. Overall, I mainly designed the system for controlling these switches and developed some algorithms for optimizing the best imaging positions.”
Spencer Pozder (‘19) and Justin Xia (‘19) worked with Professor Carey Rappaport on Feasibility Investigations in Multistatic Imaging Techniques for their Research Experience. Currently, active millimeter wave radar is used for imaging objects concealed on the human body at airport security checkpoints. The current monostatic configurations are unable to accurately image objects at certain angles, give lower resolution, cost more, trigger more false alarms and have longer execution times. ALERT is interested in a multistatic configuration in an “On the Move” scanning system, capable of receiving image information from multiple angles in parallel, possibly increasing resolution and accuracy of the images produced.
The team developed a product using hardware from ALERT Industrial Partners, Rapiscan and Analog Devices, creating a functional system and imaging algorithm capable of reconstructing images. They also redesigned and relocated transmitter and receiver boards to accommodate the optimized system configuration and designed mechanical structure for holding transmitters and receivers. The “On the Move” system is currently being prototyped and patented.
In addition to this program, ALERT partner universities, including the University of Puerto Rico at Mayagüez and Notre Dame, also hosted summer REU participants in their labs.
The REU program is hosted and sponsored by the Awareness and Localization of Explosives-Related Threats (ALERT) Department of Homeland Security Center of Excellence, and the Bernard M. Gordon Center for Subsurface Sensing and Imaging Systems (Gordon-CenSSIS), a Graduated National Science Foundation Engineering Research Center.
