机载纳米箔条特性及应用

Characteristics and Application of Airborne Nano-chaff

雷达技术的日益提升,使常规箔条干扰的效能不断下降,针对箔条干扰与雷达技术发展不平衡的问题,提出一种新型箔条干扰技术——纳米箔条。分析了纳米箔条的基本特性,并引入理想箔条弹概念,研究了其散射特性。仿真结果表明:纳米箔条辐射效率较低,但装填数量的优势能够弥补该不足,并使单枚理想箔条弹雷达散射截面相比传统箔条提升明显。最后,根据纳米箔条的特点,提出了基于飞机自卫的箔条遮蔽干扰,为后续的应用研究提供一定的理论依据。

With the improvement of radar technology,performance of traditional chaff jamming is decreasing constantly.Aiming at the imbalances between the development of chaff jamming and radar technology,a new chaff jamming technology called nano-chaff is proposed.The basic characteristics of nano-chaff are analyzed before introducing the concept of ideal chaff cartridge and studying its scattering characteristics.Simulation results show that nano-chaff has low radiant efficiency,for which its advantage of loading quantity can make up.Additionally,compared with traditional chaff,it can enhance the radar cross section of single ideal chaff cartridge.Finally,according to the characteristics of nano-chaff,chaff cover jamming based on aircraft self-defense is proposed, which can provide some theory basis for applied research subsequently.
