Question 8

LOS stabilization and gimble movement

Answer 8

Stabilized by gyroscope and image motion compressor (IMC)

Torque motors drive the gimbles: two for elevation and one for azimuth.

Elevation +20 to -105 degrees

360 degrees of azimuth

Question 9

MTS Electronics Unit

Answer 9

Interfaces with HCU

1553 data bus, AVT, gimbal drive, video processing, mode control, symbol functions

Question 10

Level

Answer 10

Brightness/”black bias”

sets black bias by adjusting temperature window the MTS senses

Question 11

Gain

Answer 11

Contrast

controls temperature range for a given level

varies temperature window discrimination from 1.5 degrees C (high gain) to large window of 34 (low gain)

Question 12

Three Automatic Processing Modes

Answer 12

RAY -Rayleigh
LIN - Linear
LAP - Local area processing (usually preferred)

Question 13

RAY

Answer 13

Rayleigh

similar to LIN, but shows more contrast in darker tones

Question 14

LIN

Answer 14

Linear

sets gain/contrast and brightness/level to make use of dynamic range of display, affecting all areas of the image EQUALLY

Question 15

LAP

Answer 15

Local Area Processing

Evaluate contrast patterns on entire display, adjusts gain/contrast and level/brightness to tailor differently on different parts of the display

Question 16

Polarity

Answer 16

White hot/black hot

Warm objects are white in white hot and black in black hot

Question 17

NOHD

Answer 17

Nominal ocular hazard distance - distance from operating laser at which radiant exposure is equal to the MPE (max permissible exposure)

Eye:
LRD: 39,077.2 m
LTM: 314.84 m
ELFR: 0 m

Question 18

NUC

Answer 18

Non uniformity correction

1-pt: pixel response at one temperature
2-pt: various temperatures to be collected

Question 19

PIM/PRF

Answer 19

pulse interval modulation-code requires a keyword

pulse repetition frequency

Question 20

Laser armed

Answer 20

-129 to +123 degrees azimuth

+10 to -25 elevation

Masked everywhere else

Question 21

Modes

Answer 21

Stow
Slew
Point
Cue Point
Scan 
Auto track
Forward Pointing
Offset from forward
Off set from Auto-track
Rate
Boresight

Question 22

Stow

Answer 22

MTS LOS at position that protects MTS turret windows; video reduced to min gain and level

Question 23

Slew

Answer 23

TU controlled via slew buttom

Question 24

Cue Point

Answer 24

lat/long coordinates commanded by mission avionics (to target on tactical display)

Question 25

Point

Answer 25

MTS directed to fixed location on earth's surface

Question 26

Scan

Answer 26

move in predetermined pattern

Question 27

AVT mode

Answer 27

Automatic video track slave MTS TU based on movement of object

Question 28

Offset AVT

Answer 28

LOS remains at offset position from AVT

Question 29

Forward pointing

Answer 29

LOS along front to back axis of helo

Question 30

Offset from forward pointing

Answer 30

LOS may be directed to a position offset some number of degrees from forward

Question 31

Rate mode

Answer 31

MTS TU move at a constant rate

Question 32

GIP

Answer 32

EGI data valid WOW MTS powered and looking below horizon.

Question 33

MTS nomenclature

Answer 33

AN/AAS-44C

Question 34

Safety fan

Answer 34

Remote designator outside of +/- 30 degrees of aircraft heading

Question 35

Podium Effect

Answer 35

Blocked Reflection. When the seeker is looking for scattered laser energy, it must be able to see the reflecting surface. When a laser designates a surface that the seeker cannot see, the reflections are blocked

Question 36

CCM

Answer 36

A counter-countermeasures (CCM) feature within the missile is available. This feature allows the missile to overcome suspected active electro-optical countermeasures being used within the target area. The feature should only be used when active electronic counter-countermeasures (ECCM) is known to be deployed in the target area. - Because it may an adverse impact on missile performance.

Question 37

Backscatter

Answer 37

laser energy scattered back in the direction of the seeker by an obscurant. Since backscatter energy competes with the reflected energy from the target, a seeker may attempt to lock onto the obscurant rather than the target.
