How to represent a wave in 3D and its Interference with other waves?

I have a number of radars( 2 or more) in my model. I want to simulate the interference due to radars. I can track wave-form using a platform object. But how to do the simulation and what are the conditions the wave should satisfy?

simulation is done using the absolute value of electric field (Ex,Ey,Ez), and linear medium allows linear superposition, then a sum of existing wave is possible, the conditions needed are the polarization of the wave, amplitude, frequency and phase. generally solution of Helmholtz equation is used .

how do we represent the wave in 3D space at a given instant. Wave is an continuous object. It would be good to get a code example. Also how do waves interact.
