摘要
Abstract
Compared with the other shapes of antenna array , uniform circular array is more suitable for the application requirements of direction-finding receiver used for electronic reconnaissance .In this paper , uniform circular array is projected into non-uniform linear array which changes with the incident angle .The characteristics of wave path difference in uniform circular array with odd and even numbered sensors are analyzed , the corresponding radius selection formulas are given , and a method for representing the error trends of direction-finding with the coefficient of correlation is proposed. Equivalences in all directions, accuracy of direction-finding , characteristics of phase ambiguity and sensitivity of array element location are simulated in two different cases .Validity of the inferences and the formulas is verified through simulation .The conclusion of this paper has high referential value for shaping a uniform circular array in engineering applications .关键词
