Title:
How to reduce the antenna device and grating lobe
Document Type and Number:
Japanese Patent JP6289785
Kind Code:
B2
Abstract:
A signal combiner (33) specifies a weighting coefficient w for suppressing a grating lobe included in a composite signal S 3 obtained when combining a digital received signal S 1 and digital received signal S 2 stored by a signal calculation storage (31), from the gain in a grating lobe direction in a first radiation pattern and the gain in a grating lobe direction in a second radiation pattern, and combines the digital received signal S 1 and digital received signal S 2 stored by the signal calculation storage (31) using the weighting coefficient w.
