Ultra-Wide Band Ship Security Perimeter

"IAI and a partner company, Time Domain Corporation (TDC), are developing a new type of radio called Time-Modulated Ultra-Wideband (TM-UWB) radio. Within the last few years, low cost ultra-high precision time delays have become available, and these nowmake it possible to build UWB communication and radar systems which have no carrier frequency. The only signals transmitted are pulses. The Fourier transform of a perfect impulse is constant at all frequencies. For the pulses we are currently using (1/2ns), the energy extends approximately from .5 to 4 Gigahertz, and the energy content in any conventional frequency band is below the noise. Because all that is transmitted is binary pulses, implementation of electronically steerable phased array systems iseasy and effective. Similarly, SAR processing is relatively simple and effective. These two features of TM-UWB are exploited to yield an effective ship perimeter security system which will work in all weather, and may even be able to detect intrudersthrough non-metal obstacles such as dock decking. The same basic electronics can also be used to provide communication with sailors, and another unique feature of this technology is that the location of anyone carrying one of our UWB radios can betracked. Our partner company, Time Domain Corporation (TDC) has invested $100 million in private funds to commercialize this technology. A set of custom ASICS have reduced the electronics down
