3-D Near-Field Source Localization Using a Spatially Spread Acoustic Vector Sensor

Ting Shu et al.

Summary: This article presents a new method for 3-D localization of an acoustic source signal by estimating its azimuth-angle, elevation-angle, and radial range. The proposed method exploits a spatially spread acoustic vector sensor and considering the path attenuation and phase difference among the sensor components, a source location estimation method without resorting to self-normalization operation is derived.

Near-Field Passive Localization and Gain-Phase Compensation With Partly Calibrated Arrays

Ting Shu et al.

Summary: The localization of near-field sources is an important application of array signal processing. This paper considers a more general case, where the exact spatial geometry and partly calibrated irregular linear arrays are utilized. By exploiting a partly calibrated array with reference sensors, the source range-angle parameters are derived from a matrix pencil, and the ambiguities in source location parameter estimation are resolved.

Generalized spatial smoothing in bistatic EMVS-MIMO radar

Fangqing Wen et al.

Summary: This paper revisits the problem of multiple parameters estimation for coherent targets in bistatic EMVS-MIMO radar. Three generalized spatial smoothing estimators are proposed, which are capable of providing polarization information of the coherent targets without sacrificing it. These estimators do not require any constrain on the geometries of the Tx/Rx EMVS arrays and are computationally friendly yet retain robustness to the sensor position error.

Mixed Near-Field and Far-Field Localization and Array Calibration With Partly Calibrated Arrays

Jin He et al.

Summary: This study addresses the problem of passive localization of mixed near-field and far-field source signals in the presence of array gain-phase uncertainties. A new algorithm using partly calibrated nonuniform linear arrays is proposed to accommodate a more general situation. The proposed algorithm defines cumulant matrices and constructs matrix pencils to obtain unambiguous range and angle estimates of the near-field sources, and then calibrates array gain-phase errors using these estimates. A spectrum-MUSIC like approach is applied to estimate the angles of the far-field sources.

Summary: A blind Direction-of-Arrivals (DOAs) estimate is proposed for narrowband signals in Acoustic Vector-Sensor (AVS) arrays, utilizing a unique parametric Canonical Polyadic Decomposition (CPD) of the observations' Second-Order Statistics (SOSs) tensor. The method does not require prior assumptions on the array configuration and achieves improved accuracy compared to existing methods. Simulation experiments validate the approach, showing a significant reduction in root mean squared error.
