PHASED ARRAY ANTENNA ASSEMBLY, AND ACTIVE SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a phased array antenna assembly and an active sensor that permit the number of antenna elements to be reduced and the configuration to be simplified.SOLUTION: A phased array antenna assembly 1 has a phased array antenna 3 for transmission use in which a plurality of antenna elements 3to 3for transmission use oriented in a first direction are linearly arrayed and a phased array antenna 8 for reception use in which a plurality of antenna elements 8to 8for reception use oriented in a second direction different from the first direction are linearly arrayed. The phased array antenna assembly 1 further has scanning devices 4to 4for transmission use that independently control transmission signals Stto Stof a plurality of antenna elements 3to 3for transmission use to scan a transmission beam Bt in the first direction and scanning devices 9to 9for reception use that independently control reception signals Srto Srof a plurality of antenna elements 8to 8for reception use to scan a reception beam Br in the second direction.
