摘要
针对混凝土路面目标反雷达伪装设计问题,提出了一种基于合成孔径雷达SAR图像模拟的反雷达伪装设计方法。利用小面元法实现SAR图像的模拟,对模拟图像进行基于马尔科夫随机场模型的分割和数学形态学的操作,基于伪装设计原则进行混凝土路面的反雷达伪装设计,所设计的雷达图像能较好地与背景匹配。制备了不同类型的电磁功能混凝土试样,在外场条件下测试了其后向散射特性。实验结果表明,改变混凝土的成分能够得到不同后向散射特性的混凝土,从而表明了该设计方法的可行性。
Anti-radar camouflage design method based on synthetic aperture radar(SAR) image simulation was put forward for concrete road anti-radar camouflage. Small plane method was used for SAR image sim- ulation and the Markov random field model used for image segmentation and mathematical morphology. De- sign principle of camouflage was applied to the anti-radar camouflage design of the concrete road. The de- sign image matches with the background. Several different types of electromagnetic function concrete sam- ples were prepared. The backward scattering characteristic of them were tested in outside field. The re- sults indicate that the alternative concrete composite can achieve different backward scattering characteris- tic, and the design method is feasible.
