About Circular Array

Section 2 presents the acoustic circular array signal model in modal space. In Sect. 3, the basic concepts of CS are introduced and the acoustic circular array DOA estimation algorithm in modal space using the sparsity constraint is investigated. Section 4 analyzes the numerical results in detail using synthetic data, including spatial spectrum

Wideband sparse spatial spectrum estimation is an important direction-of-arrival DOA estimation method that can obtain a high resolution with few snapshots an. On the application of the global matched filter to DOA estimation with uniform circular arrays,quot

Uniform circular arrays UCAs can provide unambiguous 360-degree direction-of-arrival DOA estimation with the same estimation accuracy in all directions 1, 2.Owing to their superior performance and installation flexibility, uniform circular hydrophone arrays are widely applied on small platforms, such as mines and sonobuoys, to detect underwater targets.

The application of superresolution techniques to circular arrays in mode space is proposed. This formulation allows the use of algorithms that are otherwise specific to equispaced linear arrays, with the added benefit of full 360 degrees azimuth

DoA estimation requires a parametric model of the measurement data in terms of the DoAs. Consider an array of M sensors, having its reference point in the origin of a spherical coordinate system. Directions of impinging waves are defined w.r.t. this origin in terms of AoA and EoA see Figure 1.Consider P plane waves, emerging from far field sources and impinging at the array.

Direction-of-arrival DoA estimation is a critical technique in radio signal-based sensing. With the advancement of integration of sensing and communication, the demand for low-latency sensing based on wideband signals is increasing, thus efficient wideband DoA estimation with high performance is desirable. In this article, an iterative coherent signal-subspace method CSM including three
