摘要
提出一种由四个干扰阵元呈线阵不等间隔排布而构成的全新多环路反向交叉眼干扰构型,并借助通道回波、矢量合成和角度因子,分别对新构型下多环路反向交叉眼干扰的诱骗角度、诱骗距离和参数容限进行了详细的理论推导和仿真验证.仿真结果表明,在Ku波段,搭载于大型平台上的新环路构型不仅可产生很大的交叉眼增益,引导单脉冲雷达产生更大的诱骗距离和诱骗角度,而且在给定角度因子的情况下,随着干扰距离和干扰机转角的增大,角度因子等高线明显减小,多环路反向交叉眼干扰对参数容限的要求也越来越严苛.
In this paper,a new multi-loop reverse cross-eye jamming configuration is proposed,which is composed of four jamming elements arranged at unequal intervals in linear array.With the help of channel echo,vector synthesis and angle factor,the theoretical derivation and simulation verification of the decoy angle,decoy distance and parameter tolerance of the new configuration are carried out in details.The simulation results show that in Ku band,the new loop configuration mounted on a large platform can produce a large cross-eye gain,and guid the monopulse radar to generate a larger decoy distance and angle.In the case of given angle factor,with the increase of jamming distance and jammer angle,the contour of the angle factor decreases obviously,and the requirements for parameter tolerance of multi-loop reverse cross-eye jamming is becoming more and more stringent.
