Abstract

We present a measurement technique using equally spaced dipole sensors to estimate undesired electromagnetic source location emitted from electronic equipment in a short time. A compensation method for an array element pattern is also proposed. This 3-element array sensor yields experimental values of amplitude and phase differences between the received voltage of each array element and those of a single sensor placed at the same position of each array element of array sensor for cases with array spacing of 0.5 and 1 wavelengths. In addition, the received voltage after compensation using experimental data agrees with the received voltage by scanning a single sensor within 0.2dB in amplitude and 1.6° in phase.
