利用声光延迟线的距离欺骗干扰

Distance deception jamming based on acousto-optic delay line

距离欺骗干扰是雷达对抗的重要手段,延迟线是其关键技术。将声光延迟装置与固定光纤延迟相结合的混合延迟线,发挥了两者的优点,实现了较长的延迟时间以及延迟时间的连续可调。文中分析了其工作原理和性能指标,进行了延迟实验,论证了其可行性。

Distance deception jamming is the most important way for radar countermeasure, and delay line is one of its critical technologies. The delay line combining acousto- optic delay- line with fixed fiber delay line takes the advantages of each delay line. It can afford longer delay time and can be adjusted continuously. In this paper, the operation principle, performance and specifications of this kind of delay line are analyzed. We also did some experiments to prove its feasibility.
