In this correspondence, we consider suppressing noncircular interferences for global navigation satellite system receivers utilizing polarization-sensitive arrays, regarding high-dynamic scenarios. We model the widely linear array receive signal corrupted by potentially noncircular interferences. We analyze the second-order statistics of the widely linear receive signal and extend the covariance matrix taper methodology to cope with the widely linear receive signal. We further develop widely linear null broadening algorithms to suppress high-dynamic noncircular interferences. Simulation results validate the superior performance of the proposed algorithms in suppressing high-dynamic noncircular interferences.
