Title:
ARRAY ANTENNA SYSTEM
Document Type and Number:
Japanese Patent JPH1197922
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an array antenna system which is applicable to various array antenna devices in different antenna shapes and can correct the wave front of an antenna in a short time. SOLUTION: A 1st phase shift detection control means 810 places one transmission and reception module of each subarray in operation at the same time and detects a phase shift between outputted receive signals. A 2nd phase shift detection control means 820 performs control for placing one transmission and reception module of each subarray in operation at the same time and detecting a phase shift between outputted receive signals as to all the transmission and reception modules. In this detection control, the transmission and reception modules to be placed in operation are combined including at least the transmission and reception modules operated at the same time by the 1st phase shift detection control means 810. Then a phase shift adjustment control means 830 performs correction control over the antenna wave front according to the detection results of the phase shifts.
