线性多模圆阵的频率响应分析

宽带电子侦察侧向系统中线性多模圆阵是一种常用的体制，但是线性多模圆阵在实际设计使用中会发现其宽频带测向的特性与原本理论中的宽带测向结论并不一致。表现为高段频率测向的模糊和低段频率测向明显的性能下降。本文主要根据线性多模圆阵测向的理论对于整个测向过程给出完整的推导，并对于实际应用中的问题给出了理论说明和数学分析，希望能对于线性多模圆阵的进一步设计使用能够给出更多的帮助和指导。

Analysis on Frequency Response of Linear Multimode Circular Array

Linear multimode circular army is frequently used in broadband electronic reconnaissance and direction finding system, but in practical design and application,it is found that the broadband direction finding characteristics of linear multimode circular array are different from its theoretical conclusion,and the difference specifically appears as the dim of high band frequency direction finding and the performance degradation of low band frequency direction finding.This article mainly provides the complete d...
