摘　　要：设计了一种IR-UWB室内定位系统原理样机的射频收发机,发射机将1ns的窄脉冲调制到4GHz,接收机使用隧道二极管检波,检波包络通过比较器判决后将信号传给基带进行处理。所设计的系统通过测试,原理验证样机定位精度优于40cm,达到设计要求。This paper presents an IR-UWB RF transceiver for an indoor positioning principle verification prototype system. The pulse is modulated to 4 GHz in the transmitter while tunnel diode detector is used in the receiver. The signal is catched by comparator before it goes to baseband. The system works well. The positioning accuracy is better than 40 em, achieving design requirements.
