# SBIR Phase II: Terahertz Imaging Radar for Contactless Concealed Weapons Detection

> **NSF 01002526DB NSF RESEARCH & RELATED ACTIVIT** · CAMBRIDGE TERAHERTZ INC (CA) · $1,249,999

## Abstract

This Small Business Innovation Research Phase II project aims to revolutionize security screening through the development of a terahertz (THz) imaging radar system for contactless concealed weapons detection. The technology has significant potential to enhance public safety in high-security areas such as public transit and schools. By enabling non-invasive, real-time threat detection of both metallic and non-metallic objects, this innovation addresses critical needs in law enforcement and security sectors. The global market for advanced security screening solutions is projected to exceed $10 billion by 2025, with the addressable segment for this THz imaging technology estimated at $2-3 billion annually. Beyond security applications, the core technology has broader impacts across a diverse set of industries, potentially unlocking a multi-billion-dollar market opportunity. The successful commercialization of this THz technology promises to create high-skilled jobs in engineering and manufacturing while strengthening U.S. competitiveness in emerging semiconductor technologies. 

The intellectual merit of this project lies in its innovative approach to overcoming current limitations in THz imaging systems. The research objectives focus on addressing key technical challenges, including the design of a high-performance signal generator, development of a suitable product enclosure, and creation of effective signal processing models. The research will involve approaches such as adv
