Adaptation of the element radiation pattern in the SAGE algorithm for a cubical and dodecahedral receiving antenna array

For measurement purposes, not only the type of antenna but also the position and the polarisation of the antenna in the antenna array are very important. In most simulations and measurements, the antennas are having all the same polarisation and a nearly omnidirectional radiation pattern. In this paper, the radiation pattern of an antenna array will be included in the SAGE algorithm. By applying this algorithm on simulated or measured data, the time domain values of the Direction of Arrival (DOA) parameters can be determined very accurately. Here, the extracted parameters are the time delay or the distance, the azimuth angle, the elevation angle and the complex amplitude or the power for every significant path. The simulations are based on a previously described hexahedral and dodecahedral antenna array with monopole antennas in different polarisations. The simulation results show the influence of the element pattern on the performance of the SAGE algorithm.
