A Fixed Radar Antenna Apparatus Capable of Extending a Structure and Function

摘要

The present invention relates to a structure and performance extension type fixed radar antenna device, and more specifically, to a structure and performance extension type fixed radar antenna device capable of extending the structure and performance according to the use by adjusting the phase while extending the structure from the basic unit. will be. Structure and performance expansion type fixed radar antenna device includes at least two antenna modules (RM1, RM2) that can be coupled to each other; Includes a radar signal processing processor 14 that processes signals transmitted from the secondary phase shifters 13a and 13b that control the phases of the antenna units 11_1 to 11_M disposed in each of the antenna modules RM1 and RM2. In addition, the at least two antenna modules RM1 and RM2 are coupled to be separated from each other and can be operated independently.
