Fabrication-integration
Issues,Cost
• Robust
• Relatively small
• Not suitable for dynamic scenes
• Easiest to implement
• Inexpensive
• Scene and platform motion
• Beam wander not a problem or removed in software
• Misregistration is linear
• Simultaneous acquisition
• Large system size
• High mechanical flexibility and rigidity required
• Expensive
• Large
• Must register multiple FPAs
• Misregistration can be fixed
• Can be nonlinear
Division of aperture
(single FPA)
• Smaller size
• Loss of spatial resolution
• Fixed misregistration
• Small and rugged
• Fabrication difficult
• Alignment difficult
• Very expensive
• IFOVs misregistered
• Requires interpolation
• Fixed registration
• Best used at long ranges
• Easy integration
