Automotive Noise Received with a Vertical Dipole Antenna Placed above And on the Ground

Abstract

An analysis is presented based upon a modification of the model for automotive radio noise received with a vertical dipole antenna placed on the ground. The formulas for the impulse amplitude distributions (IAD's) at the input of a narrow-band receiver are derived for an elevated vertical dipole antenna when either a single or multiple motor vehicles are running on a roadway. Based upon new and previously derived formulas for a vertical receiving dipole antenna on the ground, two different series of IAD curves are calculated for automotive radio noise. Comparisons are shown between the measured and calculated curves.
