SUMMARY

The Global Hawk UAV is equipped with Raytheon electronic systems, featuring electro-optical (E-O) and infrared (IR) sensors, along with Synthetic Aperture Radar (SAR). The E-O/IR field of view is 5.1 x 5.2 mrad for visible light and 5.4 x 7.3 mrad for MWIR. The WAS mode coverage for E-O/IR and radar is 138,000 km² per day, while the spot mode allows for 1,900 spots and images daily. The radar has a range of 200 km, and the EO/IR sensor has a focal length of 1.75 m and an aperture of 29 cm.

PREREQUISITES
  • Understanding of UAV technology and specifications
  • Familiarity with electro-optical and infrared sensor systems
  • Knowledge of Synthetic Aperture Radar (SAR) functionality
  • Basic principles of field of view and resolution in imaging systems
NEXT STEPS
  • Research the specifications of Raytheon E-O/IR sensors

the global hawk have the raytheon electronic systems ISS with a E-O and IR sensors plus a SYthetic Aperture radar (SAR).
this are the Performance
E-O/IR field of view : visible 5.1 x 5.2 mrad
MWIR 5.4x7.3 mrad
radar field of regard (each side of aircraft ) +- 45°
E-O/ IR NIIRS: visible ( WAS mode) 6.0
visible (spot mode) 6.5
MWIR (WAS mode) 5.0
MWIR ( spot mode) 5.5
WAS mode coverage: E-O/IR and radar 138000 km^2/day
spot mode coverage : E-O/IR 1900 spots/day
radar 1900 images/day
MTI mode coverage E-O/IR 15000 km^2/min
range: radar 200 km
the EO/IR sensor has a focal length of 1.75 m and an aperture of 29 cm

how read this data to know from an altitude the area of coverage and the resolution ?

That information is probably classified, so you will not be able to determine it from publicly known data. You can probably google it to get unclassified estimates / guesses.
