【摘要】：机载箔条弹的质心干扰对末制导雷达的跟踪与制导构成了严重的威胁。针对时频域抗质心干扰效果不佳的问题提出了一种在极化域抗质心干扰的仿真模型,并将仿真结果进行了分析。该模型重点构建了箔条云的RCS极化散射模型和波束对云团的动态切割模型,在简化其它子模型的条件下,给出了仿真结果,研究了极化抗质心干扰成功所满足的输入条件。仿真结果表明,在雷达低视角、箔条偶极子小俯仰角分布方差的条件下增大入射极化倾角时,质心向载机方向快速移动,能够达到抗质心干扰的目的,间接证明了所建模型的正确性和极化抗质心干扰方法的可行性。
[Abstract]:The centroid of airborne chaff jamming on the homing radar tracking and guidance constitutes a serious threat. According to time-frequency domain anti centroid jamming effect problems put forward a kind of anti centroid interference in polarization domain simulation model, and the simulation results are analyzed. The model focuses on the construction of the dynamic polarization on cloud RCS chaff cloud scattering model and beam cutting model, simplified in other sub model, the simulation results are given, the input conditions of the polarization of the successful anti centroid jamming. The simulation results show that in low angle radar, chaff dipoles condition of small pitch angle distribution variance under the increase of the incident polarization angle, fast moving the centroid to load machine direction, can achieve the purpose of anti jamming, correctness and feasibility of the model are proved indirectly polarization resistance method of centroid jamming.

【正文快照】： 引言质心干扰是箔条云的一种重要的无源干扰形式,能够保护载机免受导弹的袭击,对防空作战带来了巨大的威胁[1]。现有的有关对抗箔条质心干扰的文献大都基于时频域提出了不同的算法[2-4],算法本身的抗干扰效果是不容置疑的,但是由于导弹和飞机都是高速运动体,这些算法运算量大
