Test

Question 1

Describe Emissivity

Answer 1

Emissivity is the ratio of radiation emitted by a real-world surface to the radiation emitted by a theoretical surface (blackbody) at the same temperature and under the same conditions.

Question 2

Which of the two has a lower emissivity?

Answer 2

(highest to lowest) Blackbody-Green Paint-Glass-Brick-Black Glossy Paint-Steel-Copper-Aluminium

Question 3

Draw the MTS-A

Question 4

Draw the MX-15

What is the wavelength, NOHD, beam divergence of the LRD?

Answer 5

1.064 µm

39 km

0.1 milliradians

Question 6

What is the wavelength and NOHD and skin hazard distance of the MTS-A LTM?

Answer 6

0.860 +/- 0.02 µm

300m

18m (23m)

Question 7

What is the beam divergence of the MTS-A LTM?

Answer 7

1.5 milliradians

Question 8

What is the wavelength of the ELRF?

Answer 8

1.540 µm

Question 9

What are the two modes of MTS-A navigation?

Answer 9

Internal (INAV): ARS data are derived from the MTS-A IMU and the internal GPS receiver in the EU

External (ENAV): ARS data are derived from the MTS-A IMU and C-migits GPS

Question 10

What is the wavelength and beam divergence of the MX-15 NLI?

Answer 10

0. 860 +/- 0.03 µm
1. 5 mrad horizontal and 1.0 mrad vertical

Question 11

What is the wavelength and beam divergence of the MX-15 Li-G?

Answer 11

0. 532 +/- 0.003 µm
1. 5 mrad

Question 12

What is the NOHD of the MX-15 NLI?

Answer 12

370m

Question 13

What is the NOHD of the MX-15 Li-G?

Answer 13

829m

Question 14

Describe the two types of MX-15 failures

Answer 14

Major alarm: indicates a capability loss

Minor alarm: indicates an out of tolerance condition

Question 15

Be able to match a laser and its slant range to its spot size

Answer 15

1 mrad @ 1000 ft = 1 ft spot size

example: NLI divergence (1.5 x 1.0 mrad) @ 30k feet slant =45.0 ft x 30 ft
