Q

Hawklink/datalink ship

A

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

Q

The comm relay assembly provides

A

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

Q

ISAR basics statistics

A

0 rpm

High resolution

5-160nm

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

17
Q

Can you freeze ISAR images?

A

Yes

18
Q

To generate a live ISAR image:

A

ISAR mode must be commanded while radiating in any other mode

If radiate is off, no ISAR image will be displayed

19
Q

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

A

Increase integration time

20
Q

ISAR mode works better during/if

A

During high sea states

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