title = "Spotlight SAR Signal Simulation Based on FDTD and Sub-Aperture Segmentation",
abstract = "In this paper, a high-resolution spotlight SAR signal simulation method using electromagnetic field distribution of the target calculated by FDTD is proposed. Aiming at the difficulty of introduce Doppler history into the existing SAR echo simulation methods, the extrapolation boundary setting and near-to-far transformation method is improved, then the received electric field of antenna in all azimuth can be calculated by compensating Doppler history to simulation data in single azimuth. In addition, a sub-aperture simulation method is proposed to solve the problem that the error of waveform forming method increases in the simulation of spotlight SAR echo. Numerical experiments are made and results show the accuracy of FDTD method and the feasibility of proposed method in spotlight SAR signal simulation.",
