Generalized coprime array configurations [PDF]
2014 IEEE 8th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2014 A coprime array consists of two uniform linear subarrays that con-struct an effective difference co-array with certain desirable char-acteristics. In this paper, we propose a generalized coprime array concept through the compression of the interelement ...

Beamforming interferometry bathymetry method based on multi-coprime sensor array
International Journal of Distributed Sensor Networks, 2019 Recently, coprime array has been a popular research field in the application of direction-of-arrival estimation. Compared with uniform linear array, coprime array can be used to expand array aperture with fewer sensors, and it also has a nice direction ...

Short-range Radar Detection with (M, N)-Coprime Array Configurations
Leida xuebao, 2016 An (M, N)-coprime array comprises two well-organized subarrays: an M-element and an N-element. This sparse array configuration is capable of resolving a number of remote sources up to O(MN) solely with the use of an M + N – 1 sensors, which allows the ...

Thinned coprime arrays for DOA estimation [PDF]
2017 25th European Signal Processing Conference (EUSIPCO), 2017 Sparse arrays can generate a larger aperture than traditional uniform linear arrays (ULA) and offer enhanced degrees-of-freedom (DOFs) which can be exploited in both beamforming and direction-of-arrival (DOA) estimation. One class of sparse arrays is the

L-shaped coprime array structures for DOA estimation [PDF]
Multidimensional Systems and Signal Processing, 2020 This paper proposes a new sparse array geometry for 2-D (azimuth and elevation) directionof-arrival (DOA) estimation based on coprime sampling. The proposed array structure is L-shaped coprime array (LCA) whose each portion is one dimensional coprime ...
