基于频控阵实现的射频隐身技术应用探讨
|
摘要
简要介绍频控天线阵列的基本原理及其应用前景。频控阵在天线阵元之间施加一个微小频率偏移后再辐射出去,导致其空间传播波束不但与角度有关也与距离有关。利用频控阵这一角度-距离相关性,电子装备可以实现基于频控阵列的射频隐身。主要探讨了该技术在诸多领域的应用前景。通过这些讨论,认为频控阵在不久的将来会在安全通信、探测、电子对抗等领域带来性能的大幅提升以及作战模式的跨越式改变。
The basic principle of frequency control antenna array and its application prospects is briefly introduced. The frequency control array radiates a small frequency offset between the antenna elements, and the spatial propagation beam is related not only to the angle but also to the distance. Using the angle-distance dependence of the frequency control array, the electronic equipment can realize the radio frequency stealth based on the frequency control array. The application prospects of this technology in many fields are mainly discussed. Through these discussions, the frequency control array will bring about a large performance improvement and a change in operational mode in the fields of secure communication, detection, and electronic war.
