mid-198os. Initial use was for site-specific work by commercial companies working in
the Beaufort Sea. The major advantages of SAR over SLAR were that the resolution did
not deteriorate with distance from the radar and that the radiometric balance across
the range of the radar imagery could be closely controlled, providing uniform
