RADAR DEVICE

摘要

PROBLEM TO BE SOLVED: To detect an object in a main lobe direction without misdetecting an object in a side lobe direction under an interference environment.

SOLUTION: AΣbeam received signal of a main antenna 11 and a first auxiliary beam received signal of a first auxiliary antenna 121 are input to an SLC processor 131 to suppress interference signal components in theΣbeam received signal. The first auxiliary beam received signal of the first auxiliary antenna 121 and a second auxiliary beam received signal of a second auxiliary antenna 122 are input to a SLC processor 132 to suppress interference signal components in the first auxiliary beam received signal. TheΣbeam received signal and the first auxiliary beam received signal after interference suppression are input to an SLB processor 14 to remove a side lobe received part of theΣbeam and to extract a main lobe received part thereof. A coefficient K of the SLB processing is switched in accordance with the on/off control of the SLC processing to perform coefficient setting in consideration of residual electric power after interference suppression.
