摘要

In this paper, the effects of mutual coupling on the performance of GPS anti-jam antennas are discussed. For space-only processing (SOP) based adaptive antennas operating in the presence of CW interfering signals, it is shown that the performance with mutual coupling is similar to the performance in the absence of mutual coupling. The performance of the adaptive antenna degrades when wide-band interfering signals are introduced. The degradation with mutual coupling is larger than when mutual coupling is excluded in the performance evaluation. Furthermore, it is demonstrated that the improper design of individual elements can be the cause of this performance degradation. Space-time adaptive processing (STAP) is shown to recover the lost performance that SOP based adaptive antennas incur in the presence of wide-band interference. Finally, it is demonstrated that improper element design can be a cause of performance degradation even when STAP is used.
