22087 理论推导和仿真验证表明该屏幕能对大带宽多方向、不同极化的 UHF 雷达来波信号进行频谱搬移，减缩 RCS，降低远距离移动目标的检测概率。 Theoretical derivation and simulation results show that Salisbury screen can realize the spectrum shifting for UHF radar signal with large bandwidth, multi-directional, as well as different polarizations.

22088 在低照度环境下拍摄的可见光图像可视性较差，若将其与红外图像直接融合会导致融合结果清晰度不理想。 The visibility of the visible images is not good under the poor lighting condition. If the visible and infrared images are fused directly, the resolution of the fused images is not ideal.
22089 针对这一问题，该文提出一种基于对比度增强与多尺度边缘保持分解的图像融合方法。 In order to solve this problem, a modified infrared and visible image fusion approach based on contrast enhancement and multi-scale edge-preserving is proposed.
22090 首先，在融合之前采用基于导向滤波的自适应增强算法提高可见光图像中暗区内容的可视性。 Firstly, an adaptive enhancement method based on the guided filter is adopted to enhance the visibility of dark region content in the visible image.
22091 其次，通过一种尺度感知边缘保持滤波器对输入图像进行多尺度分解。 Input images are then decomposed with a scale-aware edge-preserving filter.
22092 再次，应用频率调谐滤波构造显著图。 Subsequently, saliency maps of infrared and visible images are calculated on the basis of frequency-tuned filtering.
22093 最后，利用由导向滤波生成的权重图重构融合图像。 Finally, the fused images are reconstructed with the weighting maps.
22094 实验结果表明，所提方法不仅可以使细节信息更突出，而且还能够有效地抑制伪影。 Experiments show that the proposed scheme can not only make the detail information more prominent, but also suppress the artifacts effectively.
