1 Bar
If the radar just moves left to right and back that is considered 1 bar as it will scan just the single 4.9° slice of airspace. however, the radar can scan a larger area of vertical space if it moves down after a scan.
2 Bar
the radar scans left to right, moves down a few degrees and scans back right to left. Because the radar antenna is pointing lower the return scan looks at a different area of space than the first scan.
4 Bar
A 4 bar scan covers the most area but takes the longest to complete. A 1 bar scan covers the least area but is the fastest; the 2 bar scan falls in between. You trade off coverage for increased refresh rate of targets.
