Research on the Simulation Method of SAR Wave Imaging with Considering Velocity Bunching Effect
Because the velocity bunching effect has not been fully considered in synthetic aperture radar(SAR)wave imaging simulation technology and the simulation data cannot accurately reflect the actual SAR data,an SAR wave imaging simulation method that fully considers the velocity bunching effect is established and experimentally verified.The mean square error(MSE)between the simulation results and the theoretical results of the probability density distribution of SAR image intensity is calculated,and the MSE before and after considering the velocity bunching effect are 0.101 2,0.157 6,0.055 6 and 0.017 9,0.031 4,0.008 8 at wind speeds of 5 m/s,10 m/s and 15 m/s,respectively.The experimental results show that the proposed SAR wave imaging simulation method effectively improves the accuracy of the simulation data and is of high practical value for the application of SAR wave imaging.
