I am trying to understand the power density at the edge of the Withdraw Distance for a radar unit to ensure that any electronics I have are properly shielded and not affected by EMI. I understand that a 4 kW radar has a withdraw distance to 10W/m^2 of 1.65m. I know that the 10W/m^2 is not the average dissipated power at that point, but neither does it seem to be peak. I would assume that a short pulse width on a 4 kW radar would create more instantaneous power at this distance, though not enough to affect the body. Is there any detail on what sort of EMI it could induce at the edge of the Withdraw Distance?
