中文摘要：

被动雷达导引头使用干涉仪进行宽带测向时存在角度模糊。多基线解模糊方法受限于导引头天线安装体积和天线单元直径。探讨了基于圆阵干涉仪的宽带测向问题,提出一种快速宽频段解模糊方法,可根据入射角度选择参考基线组以实现全方位高精度测量。仿真结果表明了此方法的正确性和有效性。

英文摘要：

In a wideband passive radar seeker（PRS） system,there exists angle ambiguity when a phase interferometer is used for direction finding.The ambiguity resolution method based on multi-baseline is restricted by less antenna array volume and large antenna cell dimension.In order to solve this problem,a fast wideband ambiguity resolution method based on circular array phase interferometer is proposed,which chooses a pair of reference baselines according to the incident signal to assure omnidirectional high measurement precision.Simulation results show the correctness and effectiveness of the proposed method.
