The problem of providing robustness to the conventional narrow-band uniform linear array configuration so as to handle moving and cochannel jammers in GPS receiver is addressed here. This robustness is obtained via the use of derivative constraints in jammer directions. We develop the robust power inversion (PI) algorithm, the loading robust PI algorithm, and the robust eigenvector projection (EP) algorithm. These three algorithms are characterized by the fact that there is no need to know the directions of the GPS signals and jammers. Simulation results show that the algorithms proposed here are suitable for dealing with moving or cochannel jammers.
