Simulation algorithm for synthetic aperture imaging process

The invention provides a simulation algorithm for a synthetic aperture imaging process, which comprises the following steps: a preprocessing step, a supersampling step, a pupil dithering step, a low-resolution image generation step, an image dithering step and a downsampling step, and is characterized in that simulation for pupil dithering and image dithering is added under the condition that the simulation efficiency is not obviously reduced; relative jitter of a lens and an imaging target in a real environment is simulated, and the influence of specific jitter on the Fourier lamination imaging quality can be more completely simulated and surveyed. 本申请提出了一种合成孔径成像过程的仿真算法，包括如下步骤：预处理步骤、超采样步骤、光瞳抖动步骤、低分辨图像生成、图像抖动步骤、降采样步骤，在不明显降低仿真效率的情况下，加入了针对光瞳抖动及图像抖动的仿真，来模拟真实环境中镜头与成像目标的相对抖动，可更完备地仿真以勘定具体抖动对傅里叶叠层成像质量的影响。
