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 ...
