Direction of arrival estimation using combined coprime and nested array
Electronics Letters, 2019 A combined coprime and nested array geometry is designed and a corresponding direction of arrival (DOA) method is proposed. The proposed array has three subarrays, where two are prototype coprime subarrays, and both of them are nested to the third one ...

Semi-Coprime Array with Staggered Beam-Steering of Sub-Arrays
Sensors, 2023 A split-aperture array (SAA) is an array of sensors or antenna elements in which the array is split into two or more sub-arrays (SAs). Recently proposed SAAs, namely coprime and semi-coprime arrays, offer to attain a small half-power beamwidth (HPBW ...

Direction-of-Arrival Estimation in Coprime Array Using the ESPRIT-Based Method
Sensors, 2019 Coprime arrays have shown potential advantages for direction-of-arrival (DOA) estimation by increasing the number of degrees-of-freedom in the difference coarray domain with fewer physical sensors.

Direction of Arrival Estimation Algorithm Based on Coprime Array [PDF]
Hangkong bingqi, 2023 The coprime array has attracted extensive attention because of its flexible antenna placement form and larger array aperture compared with the uniform array, which can obtain higher degrees of freedom and reduce the cost of hardware resources.

Structured autocorrelation matrix estimation for coprime arrays [PDF]
Signal Processing, 2021 A coprime array receiver processes a collection of received-signal snapshots to estimate the autocorrelation matrix of a larger (virtual) uniform linear array, known as coarray. By the received-signal model, this matrix has to be (i) Positive-Definite, (ii) Hermitian, (iii) Toeplitz, and (iv) its noise-subspace eigenvalues have to be equal.

COPRIME ARRAY PARAMETERS OPTIMIZATION FOR DOA ESTIMATION
Iraqi Journal of Information & Communication Technology, 2021 Sparse array such as the coprime array is one of the most preferable sparse arrays for direction of arrival estimation due to its properties, like simplicity, capability of resolving more sources than the number of elements and resistance to mutual ...

Array gain of coprime arrays [PDF]
The Journal of the Acoustical Society of America, 2019 A coprime array of M + N − 1 elements is designed, using product processing (PP), to yield the same beam width as that of a full array of MN elements using conventional beamforming (CBF), while at the same time suppressing the grating lobes. The array gain (AG) for isotropic noise using conventional PP is slightly less than that obtained using CBF ...

Enhanced CACIS configuration for direction of arrival estimation
Electronics Letters, 2022 In this letter, an enhanced coprime array with compressed inter‐element spacing is designed for direction of arrival estimation. First, we analyse and conclude that the 0th sensor of coprime array with compressed inter‐element spacing is redundant for ...
