Hawklink/datalink; ISAR

Question 1

Hawklink/data link modes

Answer 1

1. ASUW

2. USW

Question 2

ASUW mode is probably

Answer 2

Using MMR/IFF + FLIR (MTS) + ESM to interrogate or identify surface targets

Question 3

USW is probably

Answer 3

Using FLIR + ESM + acoustic sonobuoys system

Question 4

C-band vs Ku-band

Answer 4

Ku-Band is superior in every sense than C-band

Ku-band has a lot more symbol exchange between ship/helo

Question 5

Hawklink/datalink control helo

Answer 5

Helo controls everything

Ship can monitor all mission displays that are active/in-use

Question 6

Hawklink/datalink ship

Answer 6

Ship has control over active interfaces within helo (which can vary based on mission)

However, in ASW the sonobuoys can NEVER be controlled by the ship…. the data received by T/R is sent to ship via datalink

Question 7

UHF secure ops has what machine in MFR?

Answer 7

Ky-58

Question 8

Ky-58 allows for what?

Answer 8

6 separate encryption keys to be loaded into ARC-210 (MFR)

Question 9

What are the crypto ports?

Answer 9

1 red = secure

1 black = unclass or not secure

Question 10

The comm relay assembly provides

Answer 10

Antenna RF and signal switching capability between MFR 1 and MFR 2

Basically we can be an operator and allow forn2 different frequencies to talk with each other

Question 11

COMSEC =

Answer 11

Communications security equipment

Question 12

Where are comsec buttons?

Answer 12

On OCP for rad1/2

Labeled SEC/CLR

Question 13

SEC =

Answer 13

Green and secure transmission

Question 14

CLR =

Answer 14

Yellow and clear = transmission is possible

Question 15

ISAR =

Answer 15

Inverse synthetic aperture radar

Question 16

ISAR basics statistics

Answer 16

0 rpm

High resolution

5-160nm

Provides 2-D image of designated surface contact for purpose of identifying ship class

Question 17

Can you freeze ISAR images?

Answer 17

Yes

Question 18

To generate a live ISAR image:

Answer 18

ISAR mode must be commanded while radiating in any other mode

If radiate is off, no ISAR image will be displayed

Question 19

How do you increase live ISAE image quality during low sea states or for low target speeds?

Answer 19

Increase integration time

Question 20

ISAR mode works better during/if

Answer 20

During high sea states

If object in question is moving signifactly or traveling at higher speed
