| 摘 要： | 在分析正弦调频干扰和方位向间歇采样转发干扰信号的干扰原理和干扰效果的基础上,发现正弦调频在二维干扰的情况下能产生大面积多虚假目标,达到有效的对真实目标进行压制式遮盖;方位向间歇采样可以在方位向产生多点虚假目标。通过有效地结合两种干扰方法的优点,达到可沿方位向有效扩展干扰范围的效果。最后,利用仿真实验验证了理论的正确性。

| Abstract: | Based on the analysis of jamming principle and the effect of sinusoidal frequency modulation jamming and azimuth intermittent sampling jamming to SAR,find out that 2-D sinusoidal frequency modulation jamming can produce many fake lay on large area,so that the real targets could be covered up effectively;Azimuth intermittent sampling jamming can make up many fake targets along the azimuth direction.The paper bands together the two methods effectively which can expand the jamming area.The simulation proves the correctness of the method. |
