Plot 1:

• 20m line over the EOS-East front lawn, 10m west of & parallel to the main mall sidewalk.
• 20m is at the south edge of the lawn.
• Trace spacing = 0.20 m,
• Antenna = 100MHz,
• Antenna spacing = 1m.

Processing:

• Gain type was “AGC”.
• No other processing.

Plot 2:

• Same data as plot 1.
  

Processing:

• Gain type was “SEC” to emphasize later arrivals, and suppress early returns.
• Three-point moving average(smoothing) was applied down each trace.

Plot 3:

• Same data as profile 1.
  

Processing:

• Same gain as plot 2.
• Four point moving average (smoothing)
• down each trace.
• Adjacent trace stacking was performed with 4 data traces for each plotted trace. Observe how this emphasizes flat features at the expense of other signals.
