Power Density Calculator

A-INFO's Power Density Calculator is designed to give the power density,  in Watts per square meter, at a given distance, output power and antenna gain. Please note that this calculator is only valid for far-field calculations.

Power Density in radar applications, is typically described by the non-directional power density multiplied by the gain of the radar. Notice that the distance D is an exponential component to the equation, due to the three-dimensional "spreading" of the waveform as it propagates through space.
