Non-Coherent Direction of Arrival Estimation via Frequency Estimation
This letter investigates the non-coherent Direction of Arrival (DOA) estimation problem dealing with the DOA estimation from magnitude only measurements of the array output. The magnitude squared of the array output is expanded as a superposition of some harmonics. Hence, a frequency estimation approach is used to find some nonlinear relations between DOAs, which results in inherent ambiguities...
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.
متن کاملDirection-of-arrival and frequency estimation using Poisson-Gaussian modeling
We address the problem of identi cation of sinusoidal components from observed data, which is fundamental for array signal processing and spectral line decomposition. Joint detection and estimation are proposed in a uni ed Bayesian framework, so that no preliminary estimate of the number of signals is required. All unknown quantities are estimated from a unique regularized stochastic likelihood...
متن کاملSpeaker Direction-of-Arrival Estimation Based on Frequency-Independent Beampattern
The differential microphone array (DMA) becomes more and more popular recently. In this paper, we derive the relationship between the direction-of-arrival (DoA) and DMA’s frequencyindependent beampatterns. The derivation demonstrates that the DoA can be yielded by solving a trigonometric polynomial. Taking the dipoles as a special case of this relationship, we propose three methods to estimate ...
