Development requirements 
————ÉrÉH-Fequirements 
The technological requirements to build the forthcoming generation 
of imaging radars to operate from Seasat and Space Shuttle can be met with 
relatively little difficulty, but Systems of high radiometric accuracy 
remain to be developed. It is the requirements of the data user which 
need the most effort at the present time.
