In some sense achieving high resolution imagery from orbit is simpler in that SAR requires motion compensation on the order of a wavelength. Planes are subject to all sorts of motion like turbulence whereas a satellite’s motion is often far more predictable. Closing the link budget can certainly be more challenging given longer ranges and size, weight, power, and cooling constraints for satellites though.
