Figure 23
The vertical axis is labeled “meters per second” and ranges from 0 to 8 meters per second in increments of 1 meter per second. The horizontal axis is labeled “Time in seconds” and ranges from 0 to 35 seconds in increments of 5 seconds. A legend appears in the upper right with two entries labeled “Radar” and “G P S”. A solid line with circular markers labeled “Radar” begins at (4, 0.408), rises steadily through (6, 5.711), and reaches a peak at (8, 6.527). The line remains nearly flat between (8, 6.554) and (10, 6.612), then decreases sharply through (11, 5.656), (12, 3.823), and (13, 0.453). From (13, 0.432) to (32, 0.381), the line remains flat at zero. A solid line with plus-shaped markers labeled “G P S” begins at (1, 0.499), remains at zero until (4, 0.476), then rises steeply through (6, 4.612) and (8, 6.222), reaching a peak at (9, 6.902). The line then decreases through (10, 6.467), (11, 4.798), and (12, 2.825), reaching (13,0.472). A small isolated rise appears at (14, 1.065), followed by a return to (15, 0.453). Note: All numerical data values are approximated.Comparison between radar-GPS velocities, during Test 5
