Abstract

PURPOSE:To detect the direction of a purposed object to exist in a low elevation angle direction by satisfying the symmetrical condition of a radial beam to be needed to apply a FIXED BEAM system. CONSTITUTION:The plural numbers of element antennas 7 are divided into four sub-array antennas 8a-8d concerning a vertical surface and four independent distributors 9a-9d are provided to feed the respective sub-array antennas 8a-8d. Then, the hybrid circuits 10-13, which is constituted by connecting the respective distributors 9a-9d with the hybrid circuits 10-13, execute a receiving with the plural numbers of the element antennas 7. Then, prescribed addition and subtration are executed to a signal synthesized by the distributors 9a-9d and since a signal obtained from an A terminal is used as an FA beam of an equation I and a signal obtained from a D terminal is used as an FB beam of the equation I, the symmetrical condition of the equation I can be satisfied. Thus, the direction of the purposed object to exist in the low elevation angle direction can be detected by applying the FIXED BEAM system.
