PHASED ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/1990/005391
Kind Code:
A1
Abstract:
When trouble has developed in any one of many feeder systems in a phased array antenna, the development of trouble is detected by means (DET) that is provided at an important portion of each of the blocks, supply of power to the defective system is cut off by switching means (SW), and the power is consumed by a specified terminal resistor (R) so that other systems will not be affected by the trouble. Furthermore, an optimum control is carried out by controlling the power and the phase of the power supplied to the systems free of trouble.
