摘　　要：本文对超宽带(UWB)通信系统实现的关键技术,即接收机前端的超宽带脉冲信号的检测技术进行了深入讨论。根据对UWB脉冲无线电实际接收信号的时域特征提出了一种简易、新颖的高灵敏度包络检波检测方式,分析了其电路的实现与性能,并给出了实验的数据和结果。与其他方式的比较表明,该电路是一种简单实用的非相关检测方式,与其原有的基带相关处理部分结合可获得良好的超宽带信号接收效果。The key technique in Ultra- wideband（UWB） communication system, namely technique of UWB pulse signal detection and receiving, is discussed. An easy and novel method for high sensitiviy envelope detection is given according to the time domain characteristic of received signals. The realization and performance of the circuit is analysed. Meanwhile, experiment data and results are provided. Comparison with other methods indicates this circuit is an easy and useful noncorrelation detection method,and can get good performance when it cooperates with current correlation part in base band.
