Abstract

PURPOSE:To select automatically a faulty antenna element among a large number of antenna elements, by providing a horn antenna, two switches, and a directional coupler. CONSTITUTION:A horn antenna 6, switches 3 and 10, and a directional coupler 11 are provided in front of the center shaft of antenna elements 11-1n that form a phased array antenna. Then the output of a transmitter 2 is radiated from the antenna element group via a circulator 4 and by the switches 3 and 10 a duplexer 13, and received at a receiver 12 via the antenna 6 and the coupler 11. Otherwise the output is radiated through the antenna 6 and received via the antenna element group and the coupler 11. These two ways are switched each other in such constitution of the circuit, the ON/OFF of each antenna element is controlled independently based on an instruction supplied from a radar computer 7. Thus a faulty antenna element is automatically detected.
