• Gain. The gain control value changes the amount of energy radiated by increasing the

pulse width in nanoseconds.

Also displayed in the area are;

• SeaIOCardID.

• Num

• Handle

These values are returned by the radar’s digital I/O board on initialization. If the values

displayed in these boxes are not simple integers, the A/D board may not be properly setup

(consult DMT for technical assistance).

4.2.2.2 Radar Settings

The radar settings include;

• Range Bins. Defines the total number of range bins to be processed (including zero range

gate) on each dwell.

• Pulses. Defines the number of pulses to be transmitted on each dwell.

• Zero Range Gate. The “zero range gate” defines the internal delay (in ‘bins’) before the

transmitted pulse actually leaves the antenna. This is a factory-set parameter and should

not be changed. This value is normally set between 15 and 20.

• XMIT Frequency. This entry is set to the center frequency configuration of the system so

the graphing function correctly displays the Doppler information (use Change XMIT

Freq to set). Note: It is important that this number is properly set. It is used in the

calculation of the detected speed of an intruder.
