Application Number: JP,2022-114731
Category (FI): G01S13/87,G01S13/90,G01S7/02,216
Stage: PROBLEM TO BE SOLVED: To provide a radio wave transceiver that can suppress deterioration in beam quality.SOLUTION: A radio wave transceiver 2 transmits and receives codes to and from another radio wave transceiver 2 via a synchronization antenna 27, and acquires spatiotemporal difference information including both temporal difference information which is a temporal error from a radio wave transceiver 2 serving as a reference and spatial difference information which is a spatial error from the radio wave transceiver 2 serving as the reference using a spatiotemporal difference information acquisition unit 28. Based on the spatiotemporal difference information, a phase shift adjustment unit 24 acts on a phase shifter 221 of a transmitting/receiving module 22 to control an amount of phase shift of a high frequency signal emitted from a communication antenna 21 so as to correct a spatiotemporal error, and suppresses deterioration in beam quality caused by the spatiotemporal error.SELECTED DRAWING: Figure 1 (Grant)
