12058 为确保重要目标的信息安全,提出了一种二维间歇采样延迟转发的SAR干扰技术。 In order to ensure the information security of important targets, this paper proposes a two-dimensional intermittent sampling delay forwarding SAR jamming technology.
12059 该技术直接攻击SAR的脉内相干特性,使雷达在干扰机附近的距离向和方位向同时产生多个以主假目标为中心对称分布的逼真假目标串。 The technology of direct attack intra-pulse coherence properties of SAR, the radar distance near the jammer to and orientation to producing multiple symmetrical distribution for the center with the false target lifelike false target string.
12060 干扰效果取决于距离向和方位向的采样周期和占空比。 Interference effect depends on the distance and orientation to the sampling period and duty cycle.
12061 因结合延迟转发技术,产生的距离向主假目标和方位向主假目标将不再重叠,且会偏离干扰机的所在位置。 ‭Due to delay in forwarding technology, the distance to the main target and orientation to the main false target will no longer overlap, and will deviate from the location of the jammer.
