Summary:A vector sensor is composed of three electric dipoles and three magnetic loops, measuring the full six components of electric field and magnetic field at one point in the space. This paper introduces an easy way on understanding how the vector sensor receives signals, and using the basic cross-product method with considering of the antenna pattern compensation, it can give out the more exact direction of arrival of the electromagnetic wave propagated with arbitrary polarization. In the direction of arrival estimation application, usually the signal transmitted from the ground. For Low-Grazing-Angle, without considering the antenna pattern compensation, the cross-product of a reduced vector sensor can give the azimuth of the signal arrived.
