Modern aircraft use nonconducting composite materials to reduce structural weight. The inspection of dielectric materials such as aramid or fiberglass composites requires methods to examine them in place, which rules out X-Ray and tomographic methods. This chapter presents demonstrations of material penetrating radar techniques to locate manufacturing defects and parts that have deteriorated in use. Applying time–frequency analysis could provide greater NDT testing capabilities. Chapter 7, “Modeling of UWB Radar Signals for Bioradiolocation” by Lanbo Liu, presents a new approach to using UWB radar for human vital sign detection.
3 UWB Radar Technology This section presents a review of UWB radar technology including history, operating concepts, and technical definitions. 1 Ultrawideband Radar History Starting in the 1960s many researchers developed UWB signal radar and communications systems under such names as impulse, video pulse, base-band, noise, pseudorandom noise, nonsinusoidal, wideband, and so on. Barrett shows how the development of communication systems and radars goes back at least half a century. When the terms impulse and nonsinusoidal radar created confusion, then the term UWB appeared in about 1988 to describe signals with large fractional bandwidths.
