摘要
均匀圆阵列天线以其优越的系统性能在通信、雷达探测、导航制导等许多领域得到了广泛的应用。该文建立了均匀圆阵列天线的系统模型,在此模型基础上对天线的系统性能和各种误差的影响进行了仿真分析,并针对接收信号的不同类型选择了合适的算法,进而完成了波达角估计(DOA)和输出特性的仿真分析。文章中还介绍了用MATLAB实现均匀圆阵列天线(UCA)仿真系统的思路、方法及实现方案,并建立了对均匀圆阵列天线进行全面分析的模拟仿真平台,为实验室研究提供了方便的工具。
Uniform circular array has found broad applications in communication, radar, navigation, control and guide, etc. because of its good performance. The system model is built in this paper, based on which the systematic performance and the effect of errors are simulated. Then, the optimal algorithm is chosen according to different types of signals. Furthermore, the estimation of direction of arrival (DOA) and the analysis of the output character are carried out. The idea, method and realization of the uniform circular array simulation system based on MATLAB are introduced in this paper, which provide a convenient tool for the study of uniform circular array in laboratory.
