Title:
ARRAY ANTENNA SYSTEM
Document Type and Number:
Japanese Patent JPH07106839
Kind Code:
A
Abstract:
PURPOSE: To realize the confirmation of the operation of an amplifier accurately and stably without being affected by a temperature change.
CONSTITUTION: An oscillator 11 is sweep-controlled and any of plural amplifiers 151, 152,... 15N is driven selectively and an output signal swept by the oscillator 11 is led to a predetermined antenna element 161 via the amplifier 151 (or 152,..., 15N). The operation of the amplifiers 151, 152,... 15N is confirmed by detecting an output spectrum of the antenna element 161 (or 162,..., 16N) via a spectrum analyzer 18.
