摘要
SAR成像模拟在SAR系统优化设计与性能检测、目标模板制备及判读人员培训等方面起着重要作用。构建了舰船及其海面背景组合模型,基于SAR工作过程和电磁散射机理进行了SAR回波信号模拟。通过对回波进行成像处理,实现了较为逼真的海面舰船SAR成像模拟。
Synthetic aperture radar(SAR)imaging simulation plays an important role in the optimizational design and performance test of SAR systems,the preparation of target templates and the training of interpreters.The composite model of ship and its sea background have been constructed and echo signal simulation has been carried out based on SAR work progress and electromagnetic scattering.Echo has been processed to realize vivid SAR imaging simulation of ship with its sea background.
