应用超分辨率方向估计实现通信卫星干扰源定位

利用卫星天线多波束特性来获取干扰信号波达方向（DOA）信息，是实现通信卫星干扰源定位的一条新思路。本文研究了在结合卫星多波束天线模型时，利用超分辨率方向估计方法实现通信卫星干扰源精确定位的可毛生，研究表明MN和LP两种算法在用于多波束天线的DOA估计时存在着方向估计模糊，而MV和MUSIC可应用于多波束天线的二维测向；文中还讨论MV、MUSIC应用于卫星干扰源定位的性能情况，并得到一些有益的结论。

Satellite interference location using high resolution DOA estimation techniques

Using on-board multiple beam antenna (MBA) to obtain the direction of arrival (DOA) is a new method for communication satellite interference location. The availability of satellite interference location using super-resolution DOA estimation techniques in conjunction with multibeam antennas was investigated. The results show that the MinNorm (MN) and Linear Prediction (LP) algorithms exhibit source azimuth/elevation ambiguity which is manifested as annular ring peaks in a azimuth/elevation spectrum, and is not readily applied to an MBA. But the Minimum Variance (MV) and MUSIC algorithms can be directly applied to an MBA. The performance of interference location with MV and MUSIC is also addressed.
