Enhance Degrees of Freedom for Coprime Array Using OptSpace Algorithm
IEEE Access, 2019 Coprime arrays, consisting of two subarrays with a co-prime number of physical sensors, can effectively resolve the direction-of-arrival (DOA) estimation when the number of sources exceeds the sensors. However, the conventional coprime array direction of

Non-circular signal DOA estimation based on coprime array MIMO radar
EURASIP Journal on Advances in Signal Processing, 2021 Aiming at the problems of low degree of freedom, small array aperture, and phase ambiguity in traditional coprime array direction-of-arrival estimation methods, a non-circular signal DOA estimation method based on expanded coprime array MIMO radar is ...

n-tuple coprime sensor arrays [PDF]
The Journal of the Acoustical Society of America, 2017 Until now, coprime sensor arrays have used two sparsely spaced subarrays to emulate the performance of a single uniform array with many more sensors (generally on the order of the product of each subarrays' number of sensors). This allows for similar results with fewer sensors, or the observation of higher frequencies (above the Nyquist limit) with a ...

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 ...

A Multi-Layer Concept for Coprime Array to Estimate Direction of Arrival
, 2022 Coprime arrays have holes in the difference coarray, which significantly degrade the performance of the coarray-based estimators. In this paper, we propose a multi-layer concept to fill the holes and resultantly improve the direction of arrival (DOA ...
