Abstract :
Hemispherical arrays are charming in receiving and processing multiple signals with wide space distributions and thus provide robust performance for integrated navigation systems. Previous research [D. Li et al, 2005] shows this kind of array has better scanning directivity. In this paper, a geometry-optimized hemispherical array is studied on directivity and multiple signals/jammers adaptive processing. A practical switch network used to reduce activated elements number and thus cost is also proposed. Simulation examples are presented to illustrate its performance
