Abstract：

This　paper　proposes　a　time-reversal　method　that　effectively　reconstructs　sparse　sources　using　a　focal　underdetermined　system　solver　(FOCUSS).　The　TR　process　is　first　formulated　into　an　underdetermined　matrix　equation　with　the　source　amplitudes　as　the　unknowns　to　be　solved.　Since　the　unknowns　sources　constitute　a　sparse　vector,　they　are　solved　by　using　FOCUSS.　A　3D　numerical　example　is　presented　to　verify　the　effectiveness　and　advantage　of　the　proposed　method.　©　2021　Applied　Computational　Electromagnetics　Society　(ACES).
