摘　　要：基于信号分离的智能转发式单站欺骗干扰具有较强的应用前景,但对干扰器的布站位置要求苛刻。针对单站转发式欺骗干扰的布站解算问题,综合考虑初始时延设置对干扰站高度及覆盖范围的影响,提出了基于初始时延设置的布站方法,并通过蒙特卡洛方法分析不同量级时延对干扰器的位置分布及有效干扰区域的影响。仿真结果表明,在卫星位置、目标位置与虚拟点确定的条件下,初始时延增加后解算的干扰器高度将增加,干扰半径变化幅度不稳定,不利于干扰实施的稳定性,因此,布站时初始时延设定应谨慎选择。文中基于时延控制的转发式欺骗干扰理论具有一定的参考价值与借鉴意义,同时可为单站转发式欺骗干扰的工程实现提供一定的理论依据。The single-station intelligent forwarding spoofing based on signal separation has strong application prospects,but it has strict requirements on the location of jammers.Considering the influence of initial delay setting on the height and coverage of jamming stations,a new method based on initial delay setting is proposed to solve the deployment problem of single-station forwarding spoofing.Monte Carlo method is used to analyze the effect of different magnitude delay on the position distribution and effective jamming region of the jammer.The simulation results show that when the satellite position,target position and virtual point are determined,the height of jammer will increase after the initial delay increases,and the variation range of jamming radius is unstable,which is not conducive to the stability of jamming implementation.Therefore,the initial delay setting should be carefully selected when the station is deployed.The paper has a certain reference value and significance for the theory of forwarding spoofing based on delay control,and can provide a certain theoretical basis for the engineering implementation of single-station forwarding spoofing.
