摘要
在干涉仪测向接收机中,相位测量误差是影响测向精度的关键因素。文章对干涉仪的测向原理进行了分析,并从解模糊方法与阵元阵列方式对测向精度的影响进行考虑,提出了基于长短基线的圆阵干涉仪的测向方式,同时讨论了其可行性,在实际工程应用上具有一定的指导意义。
In the interferometer DF receiver,the phase measurement error is the key factor to influence the DF precision.The paper analyzes the direction finding（DF） principle of phase interferometer.Regarding of ambiguity solving and antenna array shape,the paper presents the new DF method based on long-short baseline and circular array interferometer and discusses the feasibility simultaneously,which can provide certain guiding meaning for the actual engineering application.
