ISAR
:近距离目标超高分辨率微波成像技术在安全检测、非破坏性控制、生物医学等领域中有着非常重要的应用
价值和广阔的应用前景。该文利用基于窄脉冲形式的超宽带时域雷达系统研究近距离目标的高分辨率ISAR成像,
给出了仿真和实测结果。利用转台旋转目标,基于超宽带脉冲源和超宽带收发天线以及高性能取样示波器,配以同
步触发脉冲和自行研发的数据采集软件,搭建了该时域雷达实验系统,提出了准确获取目标回波信息的实验条件,
和实现回波延时精确校正的误差补偿方法。并针对采样时间窗内的杂波干扰,讨论了时域后向投影算法(Back
Projection,BP)与背景对消技术相结合的成像算法,实现了分辨率为 8 mm 的近距离目标的成像,准确地反映了
目标的位置、形状和大小等信息。( The high resolution imaging of near field targets are interesting for security, non-destructive control and
biomedical application. In this paper, high resolution near field ISAR imaging is implemented using Ultra Wide
Band (UWB) time domain radar system. Simulation and experiment are both conducted. The target is rotated by
turntable. The system is built based on the UWB pulse source, UWB antennas, high performance sampling
oscillograph, synchronous trigger pulse and proper motion study data acquisition software. Experiment condition
and delay errors compensation method are presented to obtain accurate echo information of the target. And Back
Projection (BP) combined with background cancel algorithm is discussed considering the clutter interference in
time window. )

Natural-Image-Sketching-Production
现有自然图像素描画效果生成算法存在容易造成画面细节丢失,笔画线条单一等问题。针对这些问题,本文提出了一种改进的自然图像素描画效果生成算法,通过模拟艺术家创作素描画过程,分步生成素描画图像底纹和素描画场景笔画轮廓,采用8个方向卷积滤波提取图像中不同方向的细节信息,并使用不同长度不同粗细的笔画来模拟艺术家在创作过程中不同力度的绘画效果,最后合并素描画笔画效果和素描画图像底纹,得到与原输入自然图像内容一致,色调与艺术家绘制的素描画效果相同,笔画和底纹形式与实际素描画相似,真实感较强的素描画效果输出图像。大量实验结果表明本文方法可以生成高质量的自然图像素描画效果,与现有成熟的铅笔画生成技术相笔,本文方法具有较强的可比性。(The existing algorithms for natural image sketch production are easy to cause some problems such as the loss of image details, singleness of the stroke line. To solve these problems, this paper proposes an improved algorithm for the natural image sketch effect producing. By simulating the artist creation process of sketch, step-by-step generate image shading sketch image shading and drawing the scene outline stroke of the sketch image, using 8 directions of convolution filter to extract the details of different directions in the image, furthermore, using the stroke of different length and thickness to simulate the painting effect of different strength in the process of artist creation, finally we merge the sketch stroke effect and sketch image background to get the output image, which have consistent content with the original input image, have the same tonal effect with artists draw sketch, have the similar Stroke and background form with the actual sketch and have strong real sense in)
