基于现有的通信建模及分析软件,设计了一种实时可控的射频多辐射源半实物仿真系统.该系统在软件定义无线电架构平台上进行了开发和验证,能产生包括常规通信信号、直序扩频／跳频扩频信号、战术数据链信号、雷达信号、特殊自定义信号等多种信号样式,并能同时输出16路射频信号,每路信号的调制样式、频偏、幅度增益实时可控.实现了从计算机仿真到实时电磁波信号产生的有效结合,从而丰富了测试手段,提高了设备的可靠性和适应能力.同时,该系统具有可移植、可扩展、可升级的特点.%Based on current communication modeling and analyzing software,a real-time RF multi-emitter hardware-in-the-loop simulation system for complex electromagnetic environment is designed. It combines the computer simulation with me real-time electromagnetic waves generating, and the testing method has the advantage to enhance the reliability and adaptability. The system is developed and verified via a set of software defined radio (SDR) based platform.lt can generate signals including normal communication signals, direct sequence spread spectrum ( DSSS) / frequency hopping spread spectmm( FHSS) signals,tactical data-link signals, radar signals and special customized signals. At most 16 signals can be generated simultaneously on this platform,and every signal's modulation type,frequency offset and amplitude gain can be real-rime controlled by the software. The system can also be transplanted,extended and updated easily-
