Three-dimensional dipole source identification using two fixed receiving antennas and its new algorithm

A novel source identification algorithm has already been proposed and numerically investigated. Where, the unknown source is assumed to be either an electric or a magnetic dipole having an arbitrary location and orientation. It can be either a transient source or a continuous source having unknown spectrum. Any scatterers or media can be present in the space whenever they are reciprocal and fully known. Two receiving antennas are to be used to record the waveforms. By inverting the role of source and receiving antenna, the dipole source´s location, as well as its type and orientation, can be estimated. However, the source is assumed to be a single dipole. Here, we will introduce another new algorithm that may enable the detection of multiple dipole sources, provided they are separable on the time and frequency plane.
