The disk of the Milky Way galaxy, seen edge-on from Earth's perspective, is the bright band running horizontally down the middle.

An automatic identification algorithm for the removal of bright band from radar reflectivity data is introduced and tested by case analysis and pre-operational run.

The results show that "the bright band" and "follow-up melted stagnant layer" are clearly observed only with differential interference contrast and has bright and no cellar-columnar.
