Abstract With the success of convolutional neural network (CNN) in the field of image processing and image recognition, an improved fully convolutional neural network (FCNN) based on CNN is proposed. Although FCNN has better performance than CNN, the

Abstract To achieve the high‐resolution inverse synthetic aperture radar (ISAR) imaging of moving targets, the range Doppler method and compressed sensing technique can be used. However, those methods are generally faced with the problem of migrati

Abstract Main‐lobe blanket jamming is a challenging jamming pattern in electronic warfare. Based on the difference in spatial correlation between target echoes and jamming signals, signal cancellation has been used to suppress the main‐lobe jammi

Abstract Multi‐sensor fusion recognition is a meaningful task in ISAR image recognition. Compared with a single sensor, multi‐sensor fusion can provide richer target information, which is conducive to more accurate and robust identification. Howe

Abstract Synthetic aperture radar (SAR) images are contaminated with noise called speckle that is multiplicative in nature. The presence of speckles in SAR images makes it impossible to understand and interpret for extensive range of applications. Ho
