摘要：
In the antenna array structure of passive radar seeker, uniform circular array is usually selected. However, due to the influence of spatial distribution, missile structure and radome design constraints, the non-uniform circular array antenna array structure is needed in special cases. In this paper, the principle of direction finding ambiguity generation of multiple signal classification is described, the solution design of the maximum radius of the uniform circular array and the non-uniform circular array is analyzed, at the same time, for the non-uniform circular array structure, the ambiguity performance of the array under the maximum radius and greater than the maximum radius is compared and analyzed, the effectiveness of the theory in the nonuniform circular array is verified by simulation. This paper has a reference value for solving the ambiguity of direction finding under the arrangement of passive non-uniform circular array in engineering
