Select the type of graphical display: 

a.  Amplitude: An X-Y graph with range bin numbers (approx. in feet) across the X-axis and radar 

return value across the Y-axis. 

b.  Waterfall: Continuous time display with range bin numbers (approx. in feet) across the X-axis 

and a color-coded radar return values flowing down the top in continuous mode. 

These filter settings are applied after the data is returned from the radar: 

a.  Off: no filter is applied. 

b.  Averaging: Autoregressive smoothing filter (low-pass) over time. Enter a coefficient between 

0.000 and 1.000 and click “Apply” to smooth the radar return value over time. This will make 
abrupt changes appear more smooth 

c.  MTI: Autoregressive background subtraction filter (high-pass) over time. Enter a coefficient 

between 0.000 and 1.000 and click “Apply” to highlight changes from the previous sample over 
time. This filter makes it easier to detect sudden changes in the field of the radar. 

Clicking this button clears the graphical display area. 

The graphical display area. This is where the radar data is displayed in graphical form, either as an 
amplitude or waterfall chart. 

The status line shows the status of the radar or the last action requested, along with an icon indicating 
the run status of the radar or playback file. 

The X-axis of the display area labels the range bin (1-256) displayed horizontally. Each range bin 
represents a 1-nanosecond interval, which is roughly equivalent to 1 foot. The exact range bin intervals 
are 11.8 inches (30.0 cm) per range bin. 

Zoom horizontally up to 8 times. Once the zoom setting is greater than 1, use the scrollbar to move 
horizontally over the entire range of range bins. 

Note: If your PC is slower than 800 MHz or is very busy with other tasks, using a zoom setting of 8 
and a Sample Interval of 50 ms (in continuous mode) may result in display lag or even an I/O error, 
since the application will no longer be able to keep up with the incoming data stream. 

Switches between active radar and playback modes: 

a.  Radar: Data is displayed from the actual radar unit attached to the computer.
