中文摘要:
      针对常规恒虚警率(CFAR)方法对低信杂比合成孔径雷达(SAR)图像舰船目标检测效果不佳的问题,提出一种结合空间信息的星载SAR图像舰船目标检测方法。该方法通过将像素的空间信息与灰度信息相结合构造联合图像,以提高目标与背景的对比度,然后对联合图像进行CFAR检测。基于不同分辨力实测星载SAR图像舰船目标检测的实验结果表明,与直接基于CFAR的方法相比,该方法对低信杂比SAR图像具有更好的检测性能。
英文摘要:
      A ship detection method from spaceborne Synthetic Aperture Radar(SAR) imagery combined with spatial information is proposed. It combines the spatial and gray information to construct a combined image to enhance the contrast, followed by a Constant False Alarm Rate(CFAR) detection. Experimental results based on various real data demonstrate that compared to the conventional CFAR, the proposed method performs well in low SCR images in different resolutions.
