摘要
针对合成孔径雷达-地面运动目标指示(SAR-GMTI)的快速发展,有效的干扰措施将是对抗SAR-GMTI的关键。虚假运动目标干扰能够产生逼真的虚假目标,但产生的虚假目标数量有限;噪声卷积干扰能够获得雷达匹配的处理增益,并且能够产生压制式的干扰效果。结合2种干扰特性,提出一种对SAR-GMTI的噪声卷积密集假目标干扰技术,该干扰技术能够产生大量的虚假运动目标,并且兼具欺骗式和压制式干扰效果。计算机仿真表明了该技术的有效性。
Aiming at the rapid development of synthetic aperture radar-ground moving-target indication （SAR-GMTI）,effective jamming countermeasure will be the key against SAR-GMTI. False moving target jamming can generate realistic false targets, but the false target number is limited noise convolution jamming can obtain suited radar processing gain,and can generate the suppression jamming effect. Combining with two kinds of jamming specialities,this paper proposes a kind of noise convolution dense false targets jamming technique against SAR-GMTI. The jamming technique can generate a large number of false moving targets, has deceptive jamming effect and sup- pression jamming effect. Computer simulation verifies the validity of the technique.
