MTS Flashcards
MTS synopsis
Multipurpose EO, IR imaging sensor that provides long-range surveillance, high-altitude TA, tracking, laser-range finding, and laser target designation
Two components of the MTS
Electronics Unit
Turret Unit
Operating limits
50k ft
LRD<M: 45k ft
-40-55’C w/o restrictions
OSHA class laser: 4
10mins on, 10mins off
Filter Wheel Assembly
Optical path (wavelength) for DTV & SWIR
- CL (clear)
- IC (IR Cut)
- YAG
- VC (Vis Cut)
DTV
Targeting DTV & VNIR
Visible light and Near IR
FIVE FOV including 2&4x zoom
Color tracking
MWIR
-Visible representation of a thermal scene
-below the longest wavelength (deepest red) visible to the human eye
-received by a mirror lens & a beam splitter
LWIR
Enabled via a FCB
Emphasizes slight differences in surface temp (ideal for pax)
SWIR
Links visible and thermal bands
Better in adverse wx
LRD spot is visible
Push to focus & range assist focus
Commanded by 1553 bus ONLY
Push: one-time sweep
Range: continuous adjustment, ULTW DTV not capable of
Exposure
Determines how much light is used to make an image
Manual exposure range: 000-255
Image fusion/blending
Combine MWIR w/either DTV or SWIR
Not supported in ULTW or WIDE
Auto is always LAP
Man is always manual
Four types of Image Processing Modes
LAP (local area processing)
LIN (linear)
RAY (Rayleigh)
Manual
DTV color adjust
Compensates for blue haze during low light conditions and long slant ranges
Non-Uniformity Correction (NUC) Types
-External (ENUC): 10seconds
-Multi-Point (MNUC): needed for any two adjacent FOVs
-Scene-Based (SBNUC): IR only, reduces motion blur
-DTV
-Uber (UBER NUC): NAR&ULTN NUC
Split-Screen
Simultaneous viewing of MWIR with either DTV or SWIR
Sensor-to-sensor Auto Alignment (SSAA)
Aligns DTV & SWIR with MWIR by electronically shifting DTV & SWIR center
Ensures laser spot is properly aligned
HUD graphic “FULL ALGN COMPLETE” will show if successful
LRD
Guided munitions
Slant range data
LTM
Acts as an invisible pointer
Visible w/NVG
Fast blink: 3x per 1 sec
Slow blink: 1x per 2 sec
ELRF
Eyesafe
Provides Slant range data
Laser Transceiver Unit (LTU)
Located in TU
Provides power & control signals to LRD<M
At what speed does the system prevent arming the lasers
<50 knots
MTS Attitude Reference System (ARS)
Software application that continuously electronically aligns MTS, Inertial Measurement Unit (IMU), and platform nav systems
