Information Warfare Sensor and Wireless Network Using Time-Modulated Ultra-Wideband

"During Phase I , IAI performed link budget analysis for using TM-UWB radios in IW sensor scenarios. We showed that 25mbps at 5miles is achievable in the near future. We have conductedextensive comparison of comparison of different antennaconfigurations, including diamond dipole antenna, Broadspecantenna, corner reflectors, and dish reflectors. We alsodeveloped several radio control programs to demonstrate theintegration of UWB's ranging and communication capability. Forexample, users can transfer files or send real-time messageswirelessly while tracking the distance between two radios.Another major effort we did for Phase I was to optimizecommunication performance of current UWB hardware. Weexperimentally evaluate several different communication schemes,and system parameters. We were able to obtain up to 1.25 mbpsover more than 200 feet with current UWB radios. In many IWapplications, moving (air or ground) vehicles are used to collectthe sensor data, so it is important to make sure radios canacquire signals and remain locked at higher speed. Therefore, wehave evaluated effects of vehicle motion on UWB communication.The results showed that UWB radios can work at more than 35 milesper hours. Higher speed tests will be conducted in Phase II.BENEFITS: While IW sensors do not represent a very large commercial market, the basic technology has very large commercial potential.
