3. Click PREVIOUS or NEXT to view any other profiles that your ship’s computer has selected from
the profile database.
4. When you decide which profile most closely matches that of the selected contact, leave that
class name in the Classification window and make a note of the Track ID or bearing of the
contact.
5. Go to the Nav map to complete the classification process.
On the Nav Map:
1. Select the symbol of the contact that you just identified in Narrowband.
NOTE: If the contact that you have classified in Narrowband has not yet been assigned a Contact ID
(S1, S2 etc), a contact ID symbol does not exist for that contact on the Nav map.You can not
complete the contact classification process on the Nav map until the contact has been
assigned a Contact ID.
2. Right-click the contact’s symbol to display the Contact menu. Select Classify Contact to display
the Classification dialog.
■ If you have just come from Narrowband, the last class name you left selected in the
Narrowband Profile Selector is highlighted in the Class list when you select the same contact on
the Nav map.
NOTE: You can classify contacts in ESM, Stadimeter and Narrowband.The Classification dialog
highlights the name of the class that was most recently classified by one of these sensors
whenever you select that contact on the Nav map.
3. Assign a level of confidence in your classification. Click LOW , MEDIUM or HIGH .
4. Assign an alliance to the contact. Click ALLIED , THREAT , NEUTRAL or UNKNOWN .
5. Click OK .
■ The classification you have assigned to the contact now appears in the Navigation Data Display
and the 3D model of that class appears in the 3D view when that contact is selected on the Nav
map.
DEMON SONAR STATION
DEMON is an acronym for Demodulated Noise.The DEMON function is used primarily to determine
the contact’s speed.This is important information when establishing an accurate firing solution and
once determined here the value can be entered in the speed field in your TMA solution.While
DEMON cannot help you establish the specific class of a contact,it can help you narrow in on the
type of platform that is selected. See Classification using DEMON later in this chapter.
The main component of the DEMON Station is the DEMON Waterfall Display.The waterfall display
separates the selected signal into demodulated components. On the display, the horizontal axis
represents frequency and the vertical axis represents time.When a contact is selected its signal
appears as parallel vertical lines in the waterfall.The number of lines that appear depends on the
number of propeller blades the contact has.The line farthest left represents the shaft speed. Each
line to the right of the “shaft” line represents one propeller blade.The Seawolf DEMON Waterfall
Display is seen here.The DEMON waterfall functionality is the same on all controllable subs.
