Figure 4
In the center is a tall vertical flowchart composed of stacked rounded rectangular boxes connected by vertical segments and arrows. On the left side of the top section, left-aligned text reads, “Front End Radar Processing”. To the right of this text, a rounded rectangular text box reads, “Analog F E”. Directly below it, a rounded rectangular text box reads, “Digital F E”. A vertical connector leads downward from “Digital F E”. A horizontal dashed line spans across the diagram at this level. On the far left, aligned with this level, text reads, “A D C Samples”. Below, on the left side, left-aligned text reads, “Low Level Radar Processing”. Centered in this section, a rounded rectangular text box reads, “Range slash Doppler F F T”. A vertical connector leads downward to another rounded rectangular text box that reads, “Range slash Dopple slash Angle Processing”. On the right side of this middle section, vertically oriented text reads, “I V R 1642 E V M”. A horizontal dashed line spans across the diagram. On the far left, aligned with the next boundary, text reads, “Point Cloud”. Below, on the left side, left-aligned text reads, “High Level Radar Processing”. Centered beneath, a rounded rectangular text box reads, “Localization”. A horizontal dashed line spans across the diagram. On the far left, aligned with the next boundary, text reads, “Target List”. At the bottom section, on the left side, left-aligned text reads, “Matlab”. Centered are two rounded rectangular text boxes stacked vertically. The upper box reads, “Scene Interpretation”. A short vertical connector leads to the lower box, which reads, “Visualization”. On the right side of this bottom section, vertically oriented text reads, “H O S T P C”. A large downward-pointing arrow extends from below the “Visualization” box.Data processing phases. Source: Created by authors
