Compensation of Antenna Mutual Coupling Effect in the DOA Estimation for UWB Waves
We propose a novel direction-of-arrival estimation technique for ultra-wideband (UWB) electromagnetic waves, which allows for the effect of the antenna mutual coupling. This technique is comprised of a UWB interferometry, a multiple signal classification (MUSIC), and a database. The effectiveness of our scheme is demonstrated through numerical examples.
متن کاملImprove Method on DOA Estimation Accuracy of Signal Subspace Sensitivity Based on Mutual Coupling Matrix
The performance of the DOA algorithm and many other high resolution methods degrades severely with the high correlated multipath signals encountered in target low angle tracking. DOA estimation error is overcome by deriving new version of the effects model error and sensitivity analysis on subspace methods. An improved algorithm for DOA estimation of coherent signal is proposed. This algorithm ...
متن کاملDOA Estimation with Sparse Array under Unknown Mutual Coupling
In this paper, we propose a direction-of-arrival (DOA) estimation algorithm under unknown mutual coupling with a sparse linear array (SLA). We employ an SLA composed of two uniform linear arrays (ULA), and the element spacing of one of the subarrays is large enough to neglect the effect of the mutual coupling (MC). The fourth-order-cumulants (FOCs) of the received data from partial elements of ...
متن کاملSparse Bayesian Learning for DOA Estimation with Mutual Coupling
Sparse Bayesian learning (SBL) has given renewed interest to the problem of direction-of-arrival (DOA) estimation. It is generally assumed that the measurement matrix in SBL is precisely known. Unfortunately, this assumption may be invalid in practice due to the imperfect manifold caused by unknown or misspecified mutual coupling. This paper describes a modified SBL method for joint estimation ...
متن کاملExperimental study of mutual coupling compensation in smart antenna applications
This paper investigates the benefit of mutual coupling compensation via a method of moments (MoM) approach in a uniform circular antenna array operating at 1.8 GHz. This mutual coupling compensation technique is applied to a direction of arrival (DOA) study of up to two cochannel mobile users. Field measurements and computer simulations are examined to explore the assumptions of the technique a...
