A Fast Algorithm for 2D DOA Estimation Using an Omnidirectional Sensor Array
The traditional 2D MUSIC algorithm fixes the azimuth or the elevation, and searches for the other without considering the directions of sources. A spectrum peak diffusion effect phenomenon is observed and may be utilized to detect the approximate directions of sources. Accordingly, a fast 2D MUSIC algorithm, which performs azimuth and elevation simultaneous searches (henceforth referred to as A...
متن کاملFast 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 کاملFast 2D DOA Estimation Algorithm by an Array Manifold Matching Method with Parallel Linear Arrays
In this paper, the problem of two-dimensional (2D) direction-of-arrival (DOA) estimation with parallel linear arrays is addressed. Two array manifold matching (AMM) approaches, in this work, are developed for the incoherent and coherent signals, respectively. The proposed AMM methods estimate the azimuth angle only with the assumption that the elevation angles are known or estimated. The propos...
متن کاملFast Algorithm for Maximum Likelihood DOA Estimation in MIMO Array
Maximum Likelihood estimator (ML) has shown excellent performance of Direction Of Arrival (DOA) estimation in Multiple Input Multiple Output (MIMO) array. However, the computation burden of MIMO ML is very large. In order to resolve this problem, a novel MIMO Maximum Likelihood DOA Estimation based on Metropolis-Hasting Sampling (MIMO MHML) is proposed, which combines Markov Monte Carlo method ...
متن کاملDOA estimation for conformal vector-sensor array using geometric algebra
In this paper, the problem of direction of arrival (DOA) estimation is considered in the case of multiple polarized signals impinging on the conformal electromagnetic vector-sensor array (CVA). We focus on modeling the manifold holistically by a new mathematical tool called geometric algebra. Compared with existing methods, the presented one has two main advantages. Firstly, it acquires higher ...
