Custom SAR imagery products are available to users by submitting new acquisition tasking requests using either the Capella Console or Capella API. Below is a table of the available parameters.

 

Imaging Parameter 

Description 

Minimum 

Maximum 

Window Open 

The earliest user-defined time when acquisition can occur. Image acquisition can begin any time after the Window Open time up to the Window Close time. Units for this parameter is Date Time. 

n/a 

n/a 

Window Close 

The latest user-defined time when acquisition can occur. Image acquisition must occur no later than the Window Close time which effectively sets the tasking request expiration date. Units for this parameter is Date Time. 

n/a 

n/a 

Tasking Tier 

The new acquisition tasking tier (e.g. 1-Day, 3-Day, 7-Day). Units for this parameter is String. 

n/a 

n/a 

Observation Direction 

Whether spacecraft is looking Left or Right with respect to its velocity vector during image acquisition. Units for this parameter is String. Also available for Standard and Extended products tasking. 

n/a 

n/a 

Orbit State 

Whether the spacecraft is on the Ascending (South to North) or Descending (North to South) orbit during image acquisition. Units for this parameter is String. Also available for Standard and Extended products tasking. 

n/a 

n/a 

Look Angle Minimum 

Minimum angle between the sub-satellite point and image center point. Based on the full accessible look angle range of the Capella radar the smallest possible look angle is 5°. Units for this parameter is Degrees. 

5 

40 for Spot  

45 for Site 

45 for Strip  

Look Angle Maximum 

Maximum angle between the sub-satellite point and image center point. Based on the full accessible look angle range of the Capella radar the largest possible look angle is 45°. Units for this parameter is Degrees. 

5 

40 for Spot  

45 for Site 

45 for Strip  

Imaging Mode 

The radar system imaging mode (e.g. spotlight, sliding spotlight, stripmap). Units for this parameter is String. 

n/a 

n/a 

Scene Length 

Desired image scene length. This parameter is only customizable for sliding spotlight and stripmap imaging modes. Units for this parameter is Kilometers. 

5 

5 for Spot 

50 for Site 

200 for Strip 

Scene Width

Desired image scene width. This parameter is only customizable for stripmap imaging modes. Units for this parameter is Kilometers.

0.5 for Spot 

1.0 for Site 

1.2 for Strip 

3.1 for Spot 

5.0 for Site 

11.5 for Strip 

Azimuth Resolution Maximum
