Frequency and 2D Angle Estimation Based on a Sparse Uniform Array of Electromagnetic Vector Sensors
<p/> <p>We present an ESPRIT-based algorithm that yields extended-aperture two-dimensional (2D) arrival angle and carrier frequency estimates with a sparse uniform array of electromagnetic vector sensors. The ESPRIT-based frequency estimates are first achieved by using the temporal invar...
