中文说明：
合成孔径雷达（SAR)目标成像仿真，用于信号特征提取、信号消噪，在matlab环境中自动识别连通区域的大小,正确率可以达到98％，使用大量的有限元法求解偏微分方程，仿真图是速度、距离、幅度三维图像。
English Description：
Synthetic aperture radar (SAR) target imaging simulation is used for signal feature extraction and signal denoising. It can automatically identify the size of the connected area in the MATLAB environment, and the correct rate can reach 98%. A large number of finite element methods are used to solve partial differential equations. The simulation image is a three-dimensional image of velocity, distance and amplitude.
