Quiz 4 Flashcards
There are 2 primary categories of Laser Designation Operations:
- Target Acquisition
- Weapon Guidance
5 Basic considerations for using LSTs or LGWs:
- Line of Sight (LOS)
- PRF Codes
- Direction of Attack
- Laser Target Designator
- Delivery System
Podium Effect
Occurs when the reflected laser energy is blocked from the seeker
Pulse Repetition Frequency (PRF) Codes
Range 1111 to 1788
The ______ the PRF code, the _______ the repetitions, therefore:
- Lower
- Faster
- The faster the power consumption for GLD batteries
Entrapment
The absorption of laser-radiated energy from any direction.
Energy may be absorbed rather than reflected, preventing seeker acquisition.
3 Laser Designation Types:
- Continuous
- Delayed
- Redundant
LTD Beam Divergence
Increase in diameter of a laser beam with distance from exit aperture.
- Measured in milliradians (MRAD)
Spot Size (in inches) =
(.039 x MRAD) Range
SOFLAM Beam Divergence
For every 1000m, SPOT diameter increases 12 inches
Spillover Effect
Occurs when the laser spot is larger than the intended target, or when there is unsteady tracking of the target from the designator.
Targets should be greater than, or equal to, _____ laser spot size to avoid spillover.
2x
“STARE” (with laser code & reference point)
Cue the laser spot search / tracker function on the specified laser code in relation to the specific reference point.
Backscatter
Refers to a portion of the laser energy that is scattered back in the direction of the seeker by an obscurant.
2 Classifications of Lasers:
- Class 1 - Class 3R (considered eye safe)
2. Class 3B - Class 4 (hazardous to eyes and skin)
