This 2-way path loss calculator uses the familiar Friis equation for distance-related signal strength decrease, plus adds the loss due to the radar cross-section of the target. As a rule of thumb, do not specify a distance (d) less than the wavelength. Click here for more information on path loss. Click here for a 1-way (radio) path loss calculator.
