Abstract EN
The performance of antijamming is limited by channel mismatch in global navigation satellite system (GNSS) antenna arrays receivers.
Only when the amplitude and phase characteristics of each array channels are the same is the interference likely to be completely suppressed.
This paper analyzes the impact on antijamming performance of channel mismatch.
We built the model of channel mismatch and derived the impact on transfer function with space-time adaptive processor (STAP) of channel mismatch in theory.
The impact factor of channel mismatch is proposed by the fuzzy transfer function, which could directly reflect the antijamming performance under channel mismatch.
In addition, every characteristic in the channel mismatch model is analyzed.
The analysis results show that the greatest impacts on antijamming performance are the range of amplitude wave and the group delay bias, while the influence of the number of amplitudes is next.
As for the effect of group delay fluctuation is the smallest.
