现代通信系统,从战略通信系统到战术通信系统以至于每一个通信电台,无一不要求具有一定的电子防御能力。自七十年代中期以来,由于微电子学的发展和微处理机的应用,电子战对通信的威胁日益增长,面对不断改进的干扰技术,要在战场上保证良好的通信,已成为多年来最复杂,难度高的技术课题。同时,由于大规模集成(LSI)技术的进步,电荷耦合器件、声表面波器件等新器件和微处理机的出现,以及对通信系统的用途和要求增多,使扩频技术的发展速度加快,为防御电子战提供了坚强的“盾牌”。
Modern communication systems, from strategic communication systems to tactical communication systems so that every communication station, requires a certain degree of electronic defense capabilities. Since the mid-1970s, due to the development of microelectronics and the application of microprocessors, the threat posed by electronic warfare to communications has been increasing. In the face of continuously improving interference technologies, it has been for many years to ensure good communications on the battlefield The most complex and difficult technical issues. At the same time, due to advances in large-scale integration (LSI) technology, the advent of new devices and microprocessors such as charge-coupled devices and surface acoustic wave devices, and the increased use and demand for communication systems have led to the development of spread spectrum technologies, For the defensive electronic war provides a strong “shield.”
