Localization of spatially distributed near-field sources with unknown angular spread shape
We propose an estimator to localize and characterize the shape distribution of CD. This method jointly estimates angle, distance, spread angle and shape. Main idea is to estimate the shape of the distribution with an additional parameter. Accurate estimation is obtained even when the shape distribution is unknown. Good direction of arrival source separation is shown for the proposed estimator.
