Direct Localization of Multiple Noncircular Sources With a Moving Nested Array

Localization of multiple sources with moving arrays

We consider the problem of localizing multiple narrow-band stationary signals using an arbitrary time-varying array such as an array mounted on a moving platform. We assume a Gaussian stochastic model for the received signals and employ the Generalized Least Squares (GLS) estimator to get an asymptotically-e cient estimation of the model parameters. In case the signals are a-priori known to be ...

An Efficient Direct Position Determination Method for Multiple Strictly Noncircular Sources

This paper focuses on the localization methods for multiple sources received by widely separated arrays. The conventional two-step methods extract measurement parameters and then estimate the positions from them. In the contrast to the conventional two-step methods, direct position determination (DPD) localizes transmitters directly from original sensor outputs without estimating intermediate p...

Localization of multiple sound sources based on a CSP analysis with a microphone array

Accurate localization of multiple sound sources is indispensable for the microphone array-based high quality sound capture. For single sound source localization, the CSP (Cross-power Spectrum Phase analysis) method has been proposed. The CSP method localizes a sound source as a crossing point of sound directions estimated using di erent microphone pairs. However, when localizing multiple sound ...
