1 SAR成像原理的描述

• 【TGRS】Ship Detection in Large-Scale SAR Images Via Spatial Shuffle-Group Enhance Attention
  Synthetic aperture radar (SAR) has the unique advantages in that it is not limited by time of day or any type of inclement weather, has multiview imaging, and possesses certain penetration capabilities. Ship detection is a very important application of SAR image data, which plays the significant role in military and civil fields.
• 【RS2019】Depthwise Separable Convolution Neural Network for High-Speed SAR Ship Detection
  However, despite of the wide practical value in the military and civil side, up to now, SAR ship detection technology is still lagging behind optical images due to their different imaging mechanisms [10].
• 【RS】High-Speed Ship Detection in SAR Images Based on a Grid Convolutional Neural Network
  However, there are no rather mature theories and methods for target detection in SAR images up to now because the following obstacles still exist in the automatic recognition of ships in SAR images: (1) different from optical images, it is difficult to interpret SAR images intuitively; (2) due to the special imaging mechanism of SAR and the existence of speckle noise, subjective error in artificial interpretation is inevitable.
