Radar imagery uses radar to create a "picture" of the object in view of the transmitter/receiver. I'm not certain how it works, but if you can located photographs of the surface of Venus from recent spacecraft you can see examples of the results of radar imagery.
One thing I do know is that the radar "brightness" of a surface is related to it's slope and to the makeup of the surface (smooth versus rough, dust vs. rocks, etc.). So, the images don't look exactly like a photograph would but they are better in some other ways.

It means a satellite having a radar that is used to make images through a process know as synthetic aperture radar. By cpaturing both phase and magnitude information of the returning radar waves, the radar returns can be processed to render images. While the imagery isn't quite like looking at a photograph, it is representative of the scene.
