Vector　controlled-source　audio-frequency　magnetotellurics　(CSAMT)　emits　electromagnetic　waves　with　a　low　directivity　coefficient　using　a　grounded　horizontal　electric　dipole　(HED).　During　observations　in　the　far-field　region　(FfR),　only　a　fraction　of　radiation　energy　is　used.　To　improve　the　signal-to-noise　ratio　(SNR)　in　the　FfR,　it　is　necessary　to　increase　the　power　of　the　transmitter　or　shorten　the　transceiver　distance,　but　it　will　restrict　the　development　of　vector　CSAMT.　Comparatively,　the　tensor　CSAMT　uses　HEDs　in　two　directions　to　measure　geological　bodies　in　every　direction.　If　the　geological　conditions　of　two　HEDs　are　vastly　different,　it　is　easy　to　cause　issues,　such　as　an　imbalance　of　the　SNR　in　two　directions　of　the　receiving　point.　This　paper　presents　a　comparative　study　of　a　novel　arithmetic　amplitude-phase　(AAP)　weighted　beamforming　method　(BFM)　in　vector　and　tensor　CSAMT,　which　uses　multiple　HEDs　to　transmit　signals　with　controlled　amplitude　ratio　and　phase　difference　to　modulate　the　wavefront,　thereby　achieving　beam　steering　and　other　additional　functions　(such　as　amplitude　compensation).　By　concentrating　the　radiation　energy　in　the　area　of　interest　(AoI)　using　BFM,　the　SNR　can　be　largely　regulated.　The　comparative　simulation　and　analysis　demonstrate　that　the　BFM　has　advantages　in　improving　energy　utilization　and　beam　steering　in　vector　and　tensor　CSAMT.　On　the　premise　of　same　power　and　transceiver　distance,　using　the　AAP-weighted　BFM,　the　SNR　received　in　the　AoI　can　meet　the　requirements　better　than　that　received　via　the　traditional　method.
