I heard a public talk about doppler weather radar today, and have some
questions. A fair amount of time was devoted to radar signals bypassing
targets or reflecting off them. It was pretty clever. The dependency was
generally the relationship of the object's size and the length of a wave.
Polarization had some effect.

Can someone give me an idea, a simple reason or example why, for example, if
the wavelength is much shorter than the target's size, the wave will bounce
off it, and scatter from a larger object? Apparently, polarization occurs
when the wave length is much larger than the object. How does polarization
help detect certain types of objects?

Is there a fairly introductory book to these subjects or a website? The
presenter made himself very clear about how this works without much use of
math. One equation.
