Time-Matching Random Finite Set-Based Filter for Radar Multi-Target Tracking
Sensors, 2018 The random finite set (RFS) approach provides an elegant Bayesian formulation of the multi-target tracking (MTT) problem without the requirement of explicit data association.

DOA Estimation Based on Real-Valued Cross Correlation Matrix of Coprime Arrays
Sensors, 2017 A fast direction of arrival (DOA) estimation method using a real-valued cross-correlation matrix (CCM) of coprime subarrays is proposed. Firstly, real-valued CCM with extended aperture is constructed to obtain the signal subspaces corresponding to the ...

Astronomical Image Processing with Array Detectors [PDF]
, 2007 We address the question of astronomical image processing from data obtained with array detectors. We define and analyze the cases of evenly, regularly, and irregularly sampled maps for idealized (i.e., infinite) and realistic (i.e., finite) detectors. We

Holographic array processing using truncated arrays [PDF]
The Journal of the Acoustical Society of America, 1993 Imperfect knowledge of the salient characteristics of the propagation medium limits the performance of acoustic array processors at long ranges in the ocean. Holographic and phase conjugation techniques can be used to diminish the range integrated effect of the medium and reconstruct the wave front in the vicinity of a scatterer or other signal source.

Distributed processing of a fractal array beamformer [PDF]
, 2013 Fractals have been proven as potential candidates for satellite flying formations, where its different elements represent a thinned array. The distributed and low power nature of the nodes in this network motivates distributed processing when using such ...
