10.b. Fire Control System

Question 1

Interior Ballistics

Answer 1

Inside the gun barrel

Question 2

Exterior Ballistics: List 5

Answer 2

Outside the barrel (environmental)

Gravity
Drag
Wind
Drift
Croiolis

Question 3

Non-Inertial (unstable) reference frame

Answer 3

Fixed to the ship.

Question 4

Inertial (Stable) Reference Frame

Answer 4

At weapon station and grystabilized.

Question 5

What are the 3 processes to stabilize the FCS?

Answer 5

Conversion (From one coordinate system to another)

Transformation (Rotation of coordinate system in unstabilized frame to stabilized frame)

Translation (between different reference frames IOT account for parallax)

Question 6

What does CEROS stand for?

Answer 6

Celsius Tech Radar and Optronic Sight

Question 7

What type of transmitter does the CEROS use? Why?

Answer 7

TWT

Wide BW makes it resistant to jamming.

Question 8

What type of receiver does CEROS use?

Answer 8

Monopulse Comparator:

Several simultaneous beams to preciesly determine direction on return.

Question 9

How does the ESSM determine the velocity of the target?

Answer 9

It receives a rear reference signal and detects the illumination signal reflected from the target. It compares these frequenceis to determine the Doppler Shift.

Question 10

What is Adaptive Beam Forming

Answer 10

If you are being jammed from a certain direction, create a null in that direction.
