curve level that must be crossed before a detection is declared. Of course this is the first of
many steps used in validating the detection is a real target.

Gain is used to increase the average power of the radar. The value displayed in the textbox is the
actual pulse width in nanoseconds (10
-9
seconds). Typical values of gain are normally set to
between 100 and 300 nanoseconds. When Gain increments, the values are the valid pulses
currently wired in the radar’s waveform generator board. Many more values are available, but
must be specified upon request. DMT does not include all of the possible pulse widths settings
because it is not particularly useful. A 101 nanosecond pulse, for instance, does not really
provide measurable performance gain over a 100 nanosecond pulse. So DMT has provided only
significant jumps in performance in the Gain control.
