Description

To determine whether we can get away with a low performance ADCS module, we need to gauge the strength of post-processing algorithms to correct for extreme jitter and motion blur in the acquired datacube.

TODO

• [ ] Find papers that describe algorithms for pushbroom pointing jitter and motion blur compensation.
• [ ] Add papers to ‣.
• [ ] Gauge the feasibility of developing such an algorithm in-house in terms of development time/practicality.

Artifacts

Notes

• have not really come across the

Goals

1. How well can we correct for jitter in 1 scan line
2. How well can we correct for misaligned Scan Lines

Findings

• Goal 1, is movement while scanning 1 line. It leads to blur (motion blur)
  • Often defined as Jitter in papers
  • Is a result of the Pointing Stability of the ADCS system
• Goal 2, is for misaligned scan lines, leads to weird discontinuities in the images
  • Is a result of the Point Accuracy of the ADCS system

Conclusions So Far - Oct 22 2022

• COTS or In House system → Data Processing must implement a jitter correction algorithm (motion -blur) and might need to correct for scan line
• Need more than 2 weeks (Maybe 1 month or 2) to look into misaligned scan line and jitter papers and figure out what is feasible
  • lot’s of papers uses technique that are not feasible for us (high temporal resolution or stacked CCD)
  • they usually correct for very small jitter → < 1 pixel
