Direct position determination of wideband signals: Coherent and noncoherent approach

The localisation of wideband signals emitters can be performed using one-step techniques. Most of the one-step techniques or direct position determination methods are based on the spectral correlation matrix estimation. In order to improve accuracy of the emitter localisation, we investigate two approaches: coherent and noncoherent direct position determination of wideband signals. Using these two pre-processing techniques, wideband processing gain can be improved. In order to compare the coherent and noncoherent direct position determination of wideband signals, some simulation are performed.
