resolution: optical vs. microwave

2-D Aperture

range resolution  - look angle H - spacecraft height  - pulse length C - speed of light (sound)

azimuth resolution focussed unfocussed L - length of radar antenna  Ra L - length of radar antenna  - nominal slant range H/cos   wavelength of radar unfocussed focussed

How is the image focused in the computer?

Range Compression

phase history of point reflector parabolic approximation to range history Least-squares fit of range history for each point in DEM provides both the accurate position in range azimuth space and the Dopper centroid and rate parameters needed to focus the image. This analysis only needs to be applied to the master image.
