| Abstract: | Impulse UWB （Ultra-Wide Band） technology has many advantages over continuous wave narrow band technology in short distance wireless communication and ranging.Preliminary research is done on impulse UWB technology to provide novel technology support to future aerospace applications.The transceiver unit and the anten na of an impulse UWB system are described along with respective test results.Results of experiments show that both ultra-wide band wireless communication and high accuracy ranging at short distance are implemented successfully.A communication data rate of 100 Mbit/s and centimeter ranging accuracy have been achieved when the distance between two points is about 10 m during tests. |
