中文摘要:
      为了降低因路径引起的波程差,提出一种基于转发路径优化的交叉眼干扰结构。通过分析交叉眼信号传播路径,建立干扰信号传播路径模型。在雷达来波方向偏离交叉眼干扰天线中垂线的条件下,改变交叉眼双环路接收天线和发射天线位置,可以有效减小干扰距离较远时因波程差造成的相位变化,提高交叉眼干扰效果。仿真结果表明:在该结构下,交叉眼干扰与雷达的距离越远,波程差越小;雷达来波方向偏离交叉眼干扰天线中垂线越严重,波程差越小;当交叉眼干扰距离雷达较远(r>3 km)时,交叉眼天线中垂线附近波程差即可忽略,使干扰信号到达雷达时的相位差能够满足干扰要求。
英文摘要:
      In order to reduce the wave path difference, a Cross-eye jamming structure is proposed based on forwarding path optimization. An interference signal propagation path model is established by analyzing Cross-eye signal propagation path. Under condition of radar arrival direction deviating the perpendicular bisector of Cross-eye jamming antenna, through changing the location of double loops crossing receiving antenna and transmitting antenna, the phase changes caused by wave path-difference when interference distance is far away could be reduced and Cross-eye interference effect could be improved. The following conclusions are demonstrated by the simulation results: the farther the distance between Cross-eye jamming structure and radar is, the smaller the wave path difference is; the bigger the angle of radar incoming wave direction measured from the perpendicular direction of the Cross-eye jamming structure is, the smaller the wave path difference is; the wave path difference can be ignored when the Cross-eye jamming structure based on forwarding path optimization is far away from the jammed radar (r>3 km), where the phase difference satisfies the jamming requirement.
