VESPA (Virtual ESPRIT Algorithm) can estimate the directions-of-arrival (DOA) of radio waves by using shift invariance properties of two antenna elements called guiding sensors. This paper proposes an MP-VESPA-MG (Multiple Guiding sensors) that applies MP (Matrix Pencil) method to VESPA and further utilizes multiple pairs of guiding sensors. The DOA estimation accuracy of the method is evaluated by computer simulation.
