| 摘 要： | 为了实现对ISAR干扰,本文从目标一维距离像及ISAR运动补偿的角度,提出了基于正弦调相的ISAR干扰方法。文中对干扰信号如何影响距离像、影响运动补偿进行了详细的理论分析,给出了干扰造成ISAR图像失真的理论依据。并进行了基于实测数据的仿真实验。结果表明,基于正弦调相的ISAR干扰方法可以较好地干扰ISAR的一维距离像和最终的二维像,并具有压制干扰和类似欺骗干扰的双重效果,是一种对付ISAR的有效干扰手段。

| Abstract: | A jamming method to ISAR based on the sine phase modulated is proposed in this paper.How the jamming signal af- fects the range profile of the target and the motion compensation is analyzed in detail.The theory foundation of that jamming signal cau- ses the distortion of ISAR image is put forward as well.Furthermore,simulation experiment has been done based on the raw data.The re- sult shows that,this method can jam 1-D range profile and 2-D image of the target remarkably,and possess dual effects in both barrage and deception jamming.So it is an effective jamming means. |
