Figure 17
Two graphs are presented side by side. The vertical axis is labeled “Range in meters”. The horizontal axis is labeled “time in seconds”. The legend at the top lists “Radar” and “G P S”. On the left, the graph is labeled “(a)”. The vertical axis ranges from 20 to 29 in increments of 1. The horizontal axis ranges from 7 to 13 in increments of 1. The Radar curve starts at (8.292, 10.111), falls at (10.197, 2.294), then rises, and ends at (11.271, 6.917). The G P S curve starts at (7, 28.225), falls at (9.956, 3.725), then rises sharply, and ends at (12.015, 21.284). On the right, the graph is labeled “(b)”. The vertical axis ranges from 23 to 28 in increments of 1. The horizontal axis ranges from 19 to 23.5 seconds in increments of 0.5. The Radar curve starts at (19.596, 23.991), falls at (20.869, 22.281), then rises, and ends at (23.005, 26.822). The G P S curve starts at (19.017, 26.654), falls at (21.004, 22.364), then rises sharply, and ends at (22.987, 27.495). Note: All numerical data values are approximated.Distance comparison between radar and GPS, for (a) Test 1 and (b) Test 2
