نویسندگان
چکیده
In this paper, a fast algorithm for the Direction Of Arrival (DOA) estimation of radiating sources, based on partial covariance matrix and without eigende-composition of incoming signals is extended to two dimensional problem of joint azimuth and elevation estimation angles using Uniform Circular Array (UCA) in case of non coherent narrowband signals. Simulation results are presented with both Aditive White Gaussian Noise (AWGN) and real symmetric Toeplitz noise.

Fast Noncircular 2D-DOA Estimation for Rectangular Planar Array
A novel scheme is proposed for direction finding with uniform rectangular planar array. First, the characteristics of noncircular signals and Euler's formula are exploited to construct a new real-valued rectangular array data. Then, the rotational invariance relations for real-valued signal space are depicted in a new way. Finally the real-valued propagator method is utilized to estimate the pa...
متن کاملNovel two-dimensional DOA estimation with L-shaped array
Two-dimensional (2D) direction-of-arrival (DOA) estimation has played an important role in array signal processing. In this article, we address a problem of bind 2D-DOA estimation with L-shaped array. This article links the 2D-DOA estimation problem to the trilinear model. To exploit this link, we derive a trilinear decomposition-based 2D-DOA estimation algorithm in L-shaped array. Without spec...

In this paper, we propose a low complexity two-dimensional direction of arrival (2D-DOA) estimation in monostatic multiple-input multiple-output (MIMO) radar with double parallel uniform linear arrays.

متن کاملDirection of Arrival Estimation Based on Fourth-order Cumulant Using Propagator Method
In this paper direction-of-arrival estimation (DOA) of multiple narrow-band sources, based on higher-order statistics using propagator, is presented. This technique uses fourth-order cumulants of the received array data instead of second-order statistics (autocovariance) and then the so-called propagator approach is used to estimate the DOA of the sources. The propagator is a linear operator wh...

In this paper, we investigated the effect of real valued transformation of the spectral matrix of the received data for Angles Of Arrival estimation problem. Indeed, the unitary transformation of Partial Propagator (UPP) for narrowband sources is proposed and applied on Uniform Linear Array (ULA). Monte Carlo simulations proved the performance of the UPP spectrum comparatively with Forward Back...
