Paper Abstract

Accurately simulating the effect of atmospheric turbulence on the laser beams to make an effective compensation will improve the imaging ability of practical synthetic aperture ladar (SAL). Based on the modeling of atmospheric turbulence with phase screens generated by Monte Carlo algorithm and power spectrum method, and using the theory of Fourier propagation, the SAL backscattered signal of assumed Gaussian beam from point objects is simulated. The results show that phase distortion in atmospheric turbulence is severe that could reduce SAL imaging ability. A corresponding method, iterative Fourier phase conjugation (IFPC) algorithm, is provided to minimize the phase aberrations, and compensation results show that this algorithm can give us a better SAL solution.
