Antenna array processing by multichannel ARMA models

A parametric modelization approach is used for locating multiple sources from signals arriving on an antenna array. The sources time-series are here assumed to have been generated by a decoupled AR(MA) model excited by white noise, and the propagation medium is modelized as a multichannel FIR filter. The overoll process is consequently a multichannel linear system of particular structure. The identification is then performed by fast modelling algorithms. Preliminary simulation results are given in the annex.
