Research on the Speckle Influenced Resolution Imaging of Synthetic Aperture Imaging Ladar
Imaging process and the two-dimensional data collection influenced by space-time speckle effect for a resolution of the synthetic aperture imaging ladar (SAIL) are analyzed. Based on the previous research, the influences of the speckle effect introduced by different scopes and locations of the receiving antenna are compared. Correspondingly, the photocurrent, the compression in range direction and the final images of the resolution are simulated. Simulation results show that the image intensity of the resolution is significantly decreased, and the space-time varying speckle effects, introduced by different scopes and locations of the receiving antenna, exhibit remarkable different influences on the resolution imaging. Our research provides a certain reference for the reduction of the speckle effect in SAILs.
