摘要
相对于连续波窄带技术,脉冲超宽带技术在短距离通信及高精度测距方面具有一定优势。为了向未来航天应用提供新的技术支持,对脉冲超宽带通信及测距技术进行了初步研究。描述了系统的收发单元及天线单元,同时给出了各单元的测试结果。脉冲超宽带通信、测距实验表明,系统成功实现了短距离高速通信和高精度测距。在10m范围内通信码速率为100Mbit/s,定位精度为厘米量级。
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.
