N2 - GPS signals are very susceptible to interference due to weak satellite signal power. Multiple antenna receivers have been considered to be effective tools for interference suppression in GPS. In open loop nulling and localization schemes, we proceed with accurate interference direction- of-arrival (DOA) estimates which enable a follow-on effective interference suppression using available spatial degrees of freedom. In this paper, we consider sparse array configurations where the respective coarrays permit DOA estimation of a large number of interferers. The estimates are provided by using sparse reconstruction techniques. Guided by both minimum redundancy array and boundary array configurations, we design optimal placements of multiple GPS arrays on a regular Cartesian grid to achieve desirable performance.
