need help with ray tracing

Hello

I'm a computer science student and I am doing a project where I need
to calculate the radar cross section of an 3D object. I have to use
the ray tracing approach. So far I'm able to read the object from the
geometrical specifications given and store it in appropriate data
structures.

But now I am having problem in generating the rays given the
location of the source. I have to generate parallel rays(plane waves)
which hit the object I cannot figure out a way to do this ? Can any
one please give me some idea ? Is there some optical equation involved
which I can use ? Also, I am calculating energy as E = h * f and
attenuating it by 1/r ^2 depending on distance travelled. IS this a
right approach ?
