Decoupled 2D Direction of Arrival Estimation Using Compact Uniform Circular Arrays in the Presence of Elevation-Dependent Mutual Coupling (2010, methodology): “The open-circuit voltage method [12] is a widely used method”
An Autocalibration Algorithm for Uniform Circular Array With Unknown Mutual Coupling (2016, background): “However, in practice, the array manifold is often affected by unknown array characteristics such as mutual coupling [4], [5], which can seriously degrade the hi ghresolution algorithms’ performance [6], [7].”
Generalized Coprime Array Configurations for Direction-of-Arrival Estimation (2015, background): “Note that, as some of the sensors in a nested array are closely located, the mutual coupling effects between antennas may become significant and thus compromise the coarray reconstruction capability and the DOA estimation performance [10], [11].”
A 77-GHz FMCW MIMO Radar Based on an SiGe Single-Chip Transceiver (2009, background): “Hence, mutual coupling effects between the array elements, which possibly degrade the system’s performance [14], [15], are substantially reduced.”
Mutual Coupling in Phased Arrays: A Review (2013, methodology): “This equation is readily comparable with the expression given by Gupta and Ksienski [2] that relates the open circuited voltages, V o , with the coupled voltage vectors as”
