b. Playback: Data is displayed from a previously recorded file containing radar data. See the

Playback Screen Layout section below for details.

9. Radar Device Selection

a. The pulldown menu allows selection of the desired radar device, if more than one device is

connected. It always shows the currently open radar serial number. Selecting a different radar

using the pulldown menu automatically opens that radar unit for operation.

b. The Description shows the description string, followed by the version of the open radar unit.

c. Reset Radar button: Perform a hard-reset on the radar unit.

10. Run Radar Buttons

a. Single: Collect a single radar sample (i.e. all 256 range bins for a given snapshot) and display

the data in the display area.

b. Continuous: Start collecting continuous samples according to the Sample Interval setting and

display the data continuously in the display area.

c. Stop: When in continuous mode, stop the radar.

11. Record

Record radar data to a file for later playback. When the recording is started, a dialog box asks for a

filename.

a. Single Sample: Record a single sample into a file.

b. nnn Samples: Specify a specific number of samples to record to a file. If the radar is not in

continuous mode, continuous mode is temporarily started to record the requested samples.

c. Until Radar Stopped: Record radar samples until continuous mode is stopped. If the radar is

not in continuous mode, continuous mode is automatically started.

12. Radar Settings

Configure the operational settings of the radar device. These settings are saved in the computer’s

registry and are automatically used when the same radar is opened again.

a. DAC Thresholds: Set the linearity of the radar’s sensitivity to the return signal. You may select

linear, linear/log (linear at first, then logarithmic), logarithmic or custom. Selecting custom

shows a dialog box that allows custom linearity templates (i.e. DAC Thresholds) to be defined

and saved with user-defined names. DAC Threshold values must be between 20 and 227.

b. Tx Attenuation: Control the transmit attenuation of the radar by selecting a dB value from the

pulldown menu.

c. Rx Attenuation: Control the receive attenuation of the radar by selecting a dB value from the

pulldown menu.

d. Range Delay: Set the range offset of the first range bin returned by the radar. For example,

selecting 32 feet will cause the display to start at 32 feet along the X-axis.

e. Sample Interval: Sets the sampling interval for continuous mode. For example, 50 msec (the

default) will cause a sample to be collected and displayed 20 times per second when the radar

is in continuous mode.
