虚拟仪器技术在无线电引信射频干扰试验系统中的应用

Application of Virtual Instruments Technology to Experimental RF Jamming System for Radio Fuze

设计了一套无线电引信射频干扰试验系统,并把虚拟仪器技术运用其中,采用GPIB 总线连接试验系统的硬件实体,编制了基于 GPIB 通讯卡的软件控制平台,由该软件平台控制整个系统完成扫频式和回答式干扰,实现了试验系统的集成化和自动化。

Applying the virtual instruments technology, this paper designs a set of experimental RF jamming system for radio proximity fuzes, writes the GUI and driver programs based on the GPIB communication card by which all equipments can be connected together. The testing system can automatically fulfill two modes of jamming based on frequency sweeping and emulating echo signal from targets.
