A method of determining the source radiation pattern of at least one source ( 2 ) of electromagnetic radiation is provided. The method comprises the steps of at at least one sensor ( 3 ), measuring the electric and magnetic fields due to the at least one source; formulating a surface integral over the measured data, the measured data weighted by a Green's function and its spatial derivatives; and evaluating the surface integral at at least one location to determine the source radiation pattern at that location due to the at least one source. |
