Did you mean single pixel? Even with a single color, a camera provides a wealth of information. Radar is not quite a single pixel - there is speed, phase, and timing information - but it's much closer to a single pixel than to a monochrome camera. The driving radar I mean. The kit on used in aerospace sweeps out an area so it's more like a camera in the actual output.

Side note: Sorry about your uncle, but I do wish to point out, radar is non ionizing and extremely unlikely to cause mutation. What is more likely carcinogenic is stuff like degreasers, paints, fluids, and open burn pits the military likes to use.

If he was a radar technician, and worked close to the radar itself while it was operating, there's quite a chance this causes cancer.
