Title:
ARRAY ANTENNA MOUNTED ON AEROSPACE VEHICLE
Document Type and Number:
Japanese Patent JPH11163618
Kind Code:
A
Abstract:
To provide an array antenna light in weight and also capable of realizing stable, highly-precise beam direction.
An excitation distribution corresponding to panel distortion quantity due to environmental temperature data at which antenna elements 101 to 10n arranged on a panel are exposed and posture fluctuation data of an aerospace vehicle is obtained, and receiving modules 121 to 12n control the phase and amplitude of a sending signal and a receiving signal based on the excitation distribution, thereby setting a beam directing direction and a beam shape variably.
