Range gated imaging is a remote sensing acquisition which involves the emission of a laser pulse and an intensified camera to gate the reflected laser pulse. Range accuracy has always been an issue especially when a highly accurate reconstructed model is expected as the final outcome. The reflected pulse profile and pulse instability are among the issues that affect the range accuracy when a general solution such as constant offset is not applicable. In this paper, a study to estimate a more accurate model for the reflected pulse profile has been investigated through experiments. T Location-Scale model has been proposed to replace the Gaussian model as the general assumption for range-gated image formation model. The improvement on range accuracy which is around 0.3% has been verified through simulation based on the acquired samples. The series of range-gated images can be reconstructed into a three-dimensional depth map through range calculation. This can be used in the subsequent range reconstruction works.
