Paper Abstract

Synthetic aperture laser ladar is one of the most possible long-distance super-resolution active imaging methods. Many institutes have obtained two-dimensional synthetic aperture laser ladar’s reconstructed images. However, in these images, the laser speckle effect severely reduces the image quality. In the paper, we use mutli-receiver and multinoncoherent image superposition methods to reduce the impact of the laser speckle. According to the scalar diffraction theory, we deduced reconstructed image with the multi-receiver and the multi-noncoherent image superposition methods.
