Title:
RADIO WAVE RECEIVER/TRANSMITTER, DISTRIBUTED PHASED ARRAY ANTENNA SYSTEM, DISTRIBUTED ELECTROMAGNETIC WAVE OBSERVATION DATA COLLECTION SYSTEM, AND DISTRIBUTED SYNTHETIC APERTURE RADAR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/018794
Kind Code:
A1
Abstract:
A radio wave receiver/transmitter 2 executes code reception/transmission with another radio wave receiver/transmitter 2 through a synchronous antenna 27, and acquires, from a temporal and spatial difference information acquisition unit 28, temporal and spatial difference information including both temporal difference information indicating a temporal error from a reference radio wave receiver/transmitter 2 and spatial difference information indicating a spatial error from the reference radio wave receiver/transmitter 2. On the basis of the temporal and spatial difference information, a phase shift adjustment unit 24 controls a phase shift amount of a high-frequency signal emitted from a communication antenna 21 and suppresses reduction in beam quality due to the temporal and spatial errors, by operating a phase shifter 221 of a reception/transmission module 22 so as to correct the temporal and spatial errors.
