Ch. 6 MTS Flashcards
MTS
Multi-Spectral Targeting System
Types of lasers in the MTS
LRD (Laser Range Designator) (Class 4 Laser)
LTM (Laser Target Marker) (Class 4 Laser)
ELRF (Eyesafe Laser Range Finder)
Differences between the pilot, copilot, and SO HCUs
The SO’s HCU does not have an operable release consent switch. It can still lase.
HCU Right Control Switch, RCS up
When in navigation or attack mode, enters an unknown surface type MTS contact at the current ground intercept point (GIP). If a previously generated MTS contact is hook-selected and the MTS is not tracking, the MTS contact’s course and speed will be updated. If the MTS is tracking a previously generated MTS contact, the MTS contact’s course and speed will be automatically updated.
HCU Right switch, RCS Press
When in navigation mode activates MTS main menu if pressed for more than 1 second it will perform a 1-point nuc.
In attack mode, activates MTS weapons table.
HCU Return Switch
In Navigation Mode and attack mode, depression will cycle the MTS turret through poin, slew, and rate modes.
In offset track mode depression will switch to track mode.
Laser and cameras in the MTS turret
Midwave IR sensor 2 visible-light DTV cameras LLTV camera LRD LTM ELRF
MTS Turret Unit weight
128 pounds
MTS Warm up/Cooldwon time
At 25C (Less than or equal to 10 minutes) -40C to 55C (Less than or equal to 15 minutes)
Midwave Ir Sensor
3000nm-5000nm
Has six FOV: ULTW, WIDE, MED, NM, NAT and ULTN
Has two additional zooms: 2X and 4X
DTV Cameras
400-700nm
There are two DTVs.
The wide DTV camera has fixed optics for ULTW and achieves WIDE via electronic zoom.
The TGT Camera uses varying optics to provide the MED, NAR, and ULTN fields of view. The TGT camera also provides two electronic zooms, 2X and 4X.
LLTV Camera
700-900nm
Four optical FOVs are available: MED, NM, NAR, and ULTN. As well as two zooms, 2X and 4X.
How many motors drive the TU
3
2 for elevations
1 for azimuth
MTS Symbology
AN/AAS-44C(V)
Level
The level control sets the black bias or level fo the video signal, by adjusting the temperature window the MTS will sense
Gain
The gain controls the temperature range for a given level (brightness). The gain function can vary the temperature window discrimination from about 1.5C (High gain) to a relatively large window of about 34C (low gain)
Modes of Automatic gain and level control
Rayleigh
Linear
Local Area Processing
Local Area Processing
Preferred in most situations
Uses statistical analysis to evaluate the contrast patterns on the entire display, then performs adjustments so that the gain/contrast, level/brightness are tailored differently for different parts of the screen.
Linear (LIN)
Linear processing mode looks at the overall range of brightness and contrast of the incoming signal then sets the gain/contrast and level/brightness equally for the entire picture
Rayleigh (RAY)
RAY works similar to LIN but adds more contrast to dark areas of the picture
Level Low, Gain Low to Medium
Good for scanning for low thermal contrast targets. Shape rather than thermal signature may be key to detection.
Level Low to Medium, Gain Medium
Best overall setting for target detail. Allows you to threshold out cooler object easily
Level Medium, Gain Medium to High
Works well in heavy dust and fog.
A high gain increases noise in the scene but also increases the sensitivity of the MTS. The picture will appear grainy but it will be the best possible picture in the heavy weather mentioned.
Optimize DTV Video
To optimize DTV video, bright ness and contrast is adjustable
LTM Modes
Fast Blink
Slow Blink
Continuous
ELRF Range Finding
The ELRF will provide 12 ranges a minute
Covert Range Measurement
The MTS uses trigonometry to deliver the range to a selected object below the horizon
