The commissioning of the Linac Coherent Light Source (LCLS) injector showed unexpected coherent optical transition radiation (COTR) for an uncompressed electron bunch downstream of a dog-leg transport line. In this paper, we develop a three-dimensional analysis of longitudinal space charge microbunching to explain the phenomenon. Our analysis takes into account the transverse correlation of the longitudinal space charge field due to shot-noise startup and finite observation angles of the radiation. We also apply this analysis to the LCLS COTR observations.
