Abstract

Design constraints for optimal resolution of pushbroom scanned linear arrays are studied. Resolution and detector signal-to-noise ratio (SNR) trade-offs are analyzed with respect to detector geometry, quantum integration timing, flight dynamics, and optical point spread function. The point spread function model includes the effects of optical aberrations, diffraction limiting effects and platform vibration. Optimal resolution in the scan direction is defined for discretely sampled point sources. The system model maximizes detector responsive area in time delay and integrate (TDI) arrays under an optimal resolution constraint.
