ABSTRACT
The use of space-time adaptive (STAP) processing in conjunction with antenna arrays has been proposed to mitigate the effects of jammers and jammer multipath on GPS receivers. While adaptive array processing has been found to cancel jammers, concerns have been raised that the resulting distortion of the frequency response (across the operating band) produced by the adaptive array may be sufficient to adversely affect the nature of the crosscorrelation functions received from each GPS satellite.
