11 - Simplified IR Range Equation Flashcards
1
Q
Irradiance (E)
A
Describes the EM Power density (W/m2) at any given range
2
Q
Incident Power (Pe)
A
Total discernable power that reaches the IR imager is a function of:
- Irradiance (E)
- Effective Detector Area (Ae)
3
Q
Bandwidth Factor (F)
A
The fraction of radiation from the target that is within the sensitive band of the detector
4
Q
P E mesurable
A
Total measurable power at the sensor detector
Detection occcurs when P E measurable greater or equal to Smin
Maximum range occurs when PE Measurable = Smin
