Abstract

Abstract:

SAR image simulation is a technology that simulates SAR image features or SAR system working process on a computer platform to obtain a simulated SAR image. It overcomes the shortcomings of high cost and long period of acquiring different parameter SAR images from real SAR system, and plays an important role in SAR system development and algorithm verification. According to the simulation process, three SAR image simulation methods are introduced, their advantages and disadvantages are analyzed, and their current development status is comprehensively reviewed. Finally, the current problems are analyzed and the development trend in the future is prospected.

Key words: synthetic aperture radar, image simulation, echo simulation

摘要：

SAR图像仿真是一种在计算机平台上，通过模拟SAR图像特征或者SAR系统工作过程，从而得到仿真SAR图像的技术。它克服了真实SAR系统获取不同参数SAR图像成本高、周期长的缺点，在SAR系统研制和算法验证等方面起着重要作用。按照仿真流程，介绍了三种SAR图像仿真方法并对它们的优缺点进行了剖析，对其当前的发展状况做了较为全面的综述，对当前存在的问题进行了分析并对未来的发展趋势进行了展望。
