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.
