1 连续波主动无线电引信的工作原 理 连续发射无线电波的无线电近炸引信(RV),根据接收和反射信号变换的方法分为两类:外差式和自差式。 外差式无线电引信的目标探测器有独立的发射无线电波和接收反射的无线电波的两个通道。这种引信的天线系统由两副或更多的天线组成。一副天线(或一组天线)用于发射,另一副天线用于接收。反射信号的变换在混频器中进行,发射机功率的一小部分加至混频器作为本振电压。
1 Continuous wave active radio fuze works Continuous radio emission radio close proximity fuze (RV), according to the method of receiving and reflecting signal conversion is divided into two categories: heterodyne and self-descending. The target detector of a heterodyne radio fuze has two independent channels for transmitting radio waves and receiving reflected radio waves. The fuze’s antenna system consists of two or more antennas. An antenna (or a group of antennas) is used for transmission and the other antenna is used for reception. The conversion of the reflected signal takes place in the mixer, and a small part of the transmitter power is applied to the mixer as the LO voltage.
