Figure 9
Two graphs show (a) on the left and (b) on the right. On the left, the vertical axis, labeled “Range in meters”, ranges from 0 to 40, in increments of 5 meters. The horizontal axis, labeled “time in seconds”, ranges from 0 to 8, in increments of 1 second. The plotted line begins at (0, 10), decreases to a low region near (0.451, 4.968), then rises continuously and ends at (7.721, 37.451). On the right, the vertical axis, labeled “y in meters”, ranges from 0 to 50, in increments of 5 meters. The horizontal axis, labeled “x in meters”, ranges from negative 25 to 25, in increments of 5 meters. A fan of dashed radial lines originates from the bottom center at coordinates (0, 0) and radiates upward to the boundary with regular intervals. The plot contains several scatter markers forming a narrow vertical cluster around x approximately near 0, with most markers lying between approximately 10 meters and 40 meters vertically. Note: All numerical data values are approximated.Test 1: (a) Radar echoes of the detected object and (b) scatter plot
