I don't know, but it would be great if you explained what that means.
I did a quick web search and didn't find anything.

There is multispectral where there are N pixel values for each x/y
position, like RGB or many more bands.  But I am almost certain you
don't mean that.

Complex implies a magnitude and phase of a return signal and this makes
me think about LIDAR, except the wavelength is tiny compared to features
and ambiguity resolution seems infeasible.
