Analysis of the Dipole Circular Array in Interferometric Direction-Finding System

摘要

The interferometric method is one of the important techniques for direction finding when the high accuracy of DOA is required, since the angle of the incident wave can be determined from its phase information. An Adcock antenna system of which the short baseline is less than 0.5lambda_(min), is often used in the interferometric direction-finding technique. This kind of system has many advantages such as small size, light weight, convenient assembly, fiexible mobility. Moreover, such system can get unique results of DOA, because of none ambiguity occurred in the procedure of finding direction.
