I'm impressed! Since, I'm not an EE, is there a better antenna which could reduce the noise in the signal? It looks as if the noise comes in a pattern and I w

  Most highly accomplished EEs can't answer most questions about fields, let alone antennae design detail.

    Good engineers can do dipole approximations in their heads. This would require a computer- there are just too many internal reflections.

  No, the ripples show up for very simple reasons. Each bar is a reflection at a distance, the wider bars represent wider objects(which will reflect over a larger range of distances, since the radar beam is not very straight). He guesses what a few of the reflections are and some of it is probably the ground. The best antenna for radar is almost always a very directional one. Most radars use dish antennas of various designs. The very large majority of DIY microwave radios(more than you'd think) have horn antennas, which are desirable for their large bandwidth. You wouldn't use a yagi on a radar because its bandwidth is very limited, and bandwidth is directly related to resolution.
