Figure 12
Two graphs are presented side by side. The horizontal axis is labeled “Time in seconds”. The legend in the top-right lists “Radar“ and “G P S”. On the left, the graph is labeled “(a)”. The vertical axis, labeled “Velocity in kilometers per hour”, ranges from 0 to 25 in increments of 5. The horizontal axis ranges from 0 to 16 in increments of 2. The Radar curve starts at (0, 0), rises and peaks at (3.592, 20.243), remains nearly constant for a short duration, then decreases and ends at (9.796, 13.827). The G P S curve starts at (0.196, 0), rises and peaks at (4.441, 20.907), remains almost flat briefly, then drops at (11, 0), and ends at (12.147, 2.765). On the right, the graph is labeled “(b)”. The vertical axis, labeled “Distance in meters”, ranges from 0 to 50 in increments of 5. The horizontal axis ranges from 0 to 30 in increments of 5. The Radar curve starts at (0.214, 47.955), falls at (9.429, 22.955), and ends at (14.893, 3.636). The G P S curve starts at (0.214, 47.955), falls at (9.429, 22.955), and ends at (29.379, 4.545). Note: All numerical data values are approximated.Radar vs GPS comparison, during Test 7
