Question 5

Midwave IR sensor wavelengths

Answer 5

3000-5000 nm

Question 6

Visible DTV camera (2 of them)

Answer 6

400-700nm One (“Wide”) with fixed optics for wide/ULTW One (“TGT” targeting) with varying optics

Question 7

LLTV Camera

Answer 7

700-900nm (near IR), uses same optical path as DTV

Question 8

LOS stabilization and gimble movement

Answer 8

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

Cue Point

Answer 21

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

Question 22

Point

Answer 22

MTS directed to fixed location on earth’s surface

Question 23

Scan

Answer 23

move in predetermined pattern

Question 24

AVT mode

Answer 24

Automatic video track slave MTS TU based on movement of object

Question 25

Offset from forward pointing

Answer 25

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

Question 26

Rate mode

Answer 26

MTS TU move at a constant rate

Question 27

GIP

Answer 27

EGI data valid WOW MTS powered and looking below horizon.

Question 28

MTS nomenclature

Answer 28

AN/AAS-44C

Question 29

Safety fan

Answer 29

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

Question 30

Podium Effect

Answer 30

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 31

CCM

Answer 31

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 32

Backscatter

Answer 32

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.
