基于ISAR图像的火箭目标尺寸估计方法

ISAR image based size estimation method of rocket target

火箭目标尺寸估计具有重要的军事价值,可以此推测火箭型号及用途。文章提出了一种基于逆合成孔径雷达(inverse synthetic aperture radar,ISAR)图像的火箭目标尺寸估计方法。该方法通过图像增强、形态学滤波、图像分割等方法提取出火箭目标轮廓,在此基础上基于直线检测方法自动提取并估计火箭长度。采用实测数据对该方法进行了验证,结果表明,该方法可以由ISAR图像估计火箭目标的实际尺寸,具有较高的应用价值。

Size estimation of rocket target has important military value,and can infer the usage and type of the rocket.An inverse synthetic aperture radar(ISAR)image based size estimation method of rocket target is proposed in this paper.The outline of the rocket target was extracted by image enhancement,morphological filtering and image segmentation methods,and then the length of the rocket was estimated based on line detection method.Real application data was used for verifying the proposed method.Results indicate that the method can estimate the actual size of rocket target based on ISAR images,which has good application value.
