Land Flashcards
PAS vs RPAS
PAS: Manned
RPAS: Unmanned
How are RPAS controlled (6)
GCS Fibre Optic FSST KU SAT RPAS GDT
Describe RPAS Emergency Handling
Emergency mission
- put into orbit to wait for link
- after a period (fuel dependant), goes back to LRE
4 Traditional and 2 Non Dedicated ISR platforms
Shadow P-8 Reaper Protector —————- Typhoon F-35
Speed of light
300,000,000 m/s
What parts of the EM spectrum does Land Exploit?
Visible
Infrared
What is Vis and IR measured in?
Microns
What is LTM and how can it be seen?
Laser Target Marker
NVGs
What is LRD and what is it used for?
Laser Range Designator
Precision targeting for weapons using a PRF (Pulse Repetition Frequency)
Environmental factors that affect EO
Sun- can be dazzled
Visibility- sand and dust scatter light
Precipitation- water vapour and droplets scatter
Clouds- obscure picture, cause shadows, degradation
Fog- dense particles, unable to see
Environmental factors that affect IR
Sun- Can blind sensor
Visibility- causes scattering
Precipitation- Large droplets absorb heat, rain cools background making thermal objects stand out
Clouds- obscure picture, cause shadows, degradation
Fog- hot spot may be visible through fog
What does an object need to be seen with IR
Emissivity
When does thermal crossover occur and what is it? How can you over come it?
+/- 1 hour sunrise/sunset
Objects look the same as their radiant temps are the same
Overcome by switching polarity
