Engaging technology developed at, and licensed from Duke, STRADâs primary technical focus is the development of signal processing technology for surveillance and sensing applications. The firm's approach emphasizes the coupling of physical models, e.g. from electromagnetics or acoustics, with novel statistical signal processing methods to solve challenging real-world sensing problems. Set up to take ideas from inception, mathematical analysis and computer simulation through to rapid prototyping and verification testing, STRAD radar projects aredesigned to address problems in clutter mitigation, target height-finding, tracking, and geo-location. In the sonar area, the firm is addessing development of non-traditional approaches for submarine surveillance
