What is Range Gating in RADAR?

Its just the steps into which range is quantised by the signal processing system.

Here's an interesting read:

"Range gating" is a bit of a sloppy term, and means different things to different people. Most often range gating is used in sonar, lidar, and radar to blank out the receiver in the near field where back-scatter and clutter would overload the receiver front end. We once designed a lidar system to work in a blast furnace, and the near field dust reflects about 1000000 x the desired signal at 20m. If you are measuring range as the time to the largest reflection, you have to blank out the first 5m or so.

Blanking range spans which will overload the receiver is more often called range blanking than range gating.
