摘要
针对采用线性调频信号的双基地雷达,推导了间歇采样转发干扰数学模型。详细分析了干扰过程中雷达距离分辨力变化的影响,以及对干扰机的功率需求。仿真结果表明,间歇采样转发干扰可以产生前移的假目标,其前移距离远大于双基地雷达接收视线上的距离分辨力;通过选择合适的干扰功率,可以使得假目标幅度不小于真实目标幅度,达到有效的前移假目标干扰效果。
The mathematical model of Intermittent Sampling Repeater Jamming（ISRJ） against bistatic LFM radars is derived.The influence of the radar resolution and power requirement for jammer is analyzed in detail.The result shows that the ISRJ can produce preceded false targets and the preceded range of false target is far more than the resolution in the line of sight of the bistatic radars.Chosen proper jammer power,the amplitude of preceded false target can be bigger than that of real target and the deceptive jamming effect can be achieved.
