Abstract
We propose to develop an innovative way to wirelessly synchronize multiple RF receivers using ultra wideband (UWB) transceivers (radios). UWB spreads its energy over several Giga Hertz so it is highly LPI/LPD. This method does not rely on GPS so the synchronization will be maintained when the GPS signal is not available. A time resolution better than 1 nanosecond is achievable using existing UWB chipsets. The same link that is used for time synchronization can also carry data for two-way communication, and provide fast, accurate ranging in both Line of Sight (LOS), and non-LOS environments. The synchronization, ranging, and data link capabilities of UWB technology provide all the key elements of an extremely capable Time Difference Of Arrival Sensor. The most critical functions are already implemented in Silicon-Germanium (SiGe) chips, so the hardware to implement this time synchronization and ranging scheme can be very low-cost and simple.
