摘要
在分析了ISAR成像原理的基础上,以干扰ISAR包络对齐为出发点,提出了两种改进的移频干扰样式:固定位置移频干扰和逆向移频干扰。研究结果表明改进的移频干扰信号可以有效破坏ISAR的包络对齐,从而实现对ISAR二维成像的有效干扰。
The principle of ISAR imaging is introduced in the paper.For jamming the range alignment of ISAR,two improved shift-frequency jamming styles,Fixed-Position shift-frequency jamming and Reverse-Direction shift-frequency jamming are proposed.The research results shows that the improved shift-frequency jamming styles can break the range alignment,and jamming the 2-D image of ISAR effectively.The jamming effect of the jamming signals are validated by simulation.
