Noncircular Sources-Based Sparse Representation Algorithm for Direction of Arrival Estimation in MIMO Radar with Mutual Coupling
In this paper, a reweighted sparse representation algorithm based on noncircular sources is proposed, and the problem of the direction of arrival (DOA) estimation for multiple-input multiple-output (MIMO) radar with mutual coupling is addressed. Making full use of the special structure of banded symmetric Toeplitz mutual coupling matrices (MCM), the proposed algorithm firstly eliminates the eff...
متن کاملTwo Novel Two-Stage Direction of Arrival Estimation Algorithms for Two-Dimensional Mixed Noncircular and Circular Sources
This paper addresses the two-dimensional (2D) direction-of-arrival (DOA) estimation problem with two novel methods for mixed noncircular and circular signals. The first proposed method is named the two-stage direction-of-arrival matrix (TSDOAM) method, and the other is called the two-stage rank reduction (TSRARE) method. The proposed methods utilize both the circularity and the direction-of-arr...
متن کاملDirection-of-arrival Estimation of Wideband Sources Using Sensor Arrays
To my family. My father and mother. Especially, to my beloved wife Ji-Hyun and my precious Catherine. iii ACKNOWLEDGEMENTS When I came to Georgia Tech, I used to imagine the moment when I graduate and thought that it would take forever to finish my graduate work. Since then, five years passed fast and I have finished my thesis. While I was writing this thesis, I could not help thinking that it ...
متن کاملDirection of Arrival Estimation
We have seen that there is a one-to-one relationship between the direction of a signal and the associated received steering vector. It should therefore be possible to invert the relationship and estimate the direction of a signal from the received signals. An antenna array therefore should be able to provide for direction of arrival estimation. We have also seen that there is a Fourier relation...
متن کاملDirection of Arrival Estimation
Array Signal Processing (ASP) is a relatively new technique in Digital Signal Processing (DSP) with many potential applications in communication and speech processing. Direction of arrival (DOA) can be estimated using different techniques evolved with ASP. It is observed that subspace method provides superior performance in resolving closely spaced sources.
