Abstract：Focused on the range/time-angle-dependent signal transceiver and processing issue with the coherent frequency diversearray （FDA）radar，anFDA radar transceiver joint multi-beam designmethod based on angle-dependent matched filter（ADMF）is proposed.This method can realize equivalent transmit digital beamforming and signal pulse compression matching processing at the same time. Echo signals from different spatialangles can be processed inparallels.Combining with thejoint receivingdigital beamforming technology， it is possible to implement joint transceiver beamforming simultaneously to realize the simultaneous wide-field wide-angle coverage of multi-beam，and meet the requirement of radar wide-field search task．Simulation examples demonstrate the effectiveness of the proposed method.
