Abstract

It is a key problem to get the high resolution and large field of view of dynamic measurement in the ladar technology. In this paper, Charge Coupled Device was synthesized with seams to be a display unit. A reconstruction method is proposed which combines the principles of synthetic aperture and phase retrieval to detect the particle target. Then the non-integer pixel stitching error in a synthetic-aperture ladar with seams is corrected by a method based on the shift theorem of the Fourier transform. In the X experiment, the correlation coefficient of surface l is 0.73217 between the reconstructed image and the simulated particles target image. The pictures from the experiment depicts the particle is not only clearly visible at the normal region but also at the seams. The target information can be recovered well of the high resolution and large field of view with this method.
