Abstract: A hemi-spherical conformal array with wide-angle scanning is designed in this paper. After the selection of active region, the elements which are not contributed to the array are switched ...

Abstract: This paper considers the novel application of space-time adaptive processing (STAP) to conformal array radar. Using numerical simulation, we characterize the performance potential of two ...

Purpose: Derive the array factor for a uniform linear array (ULA), beam steering, grating lobe conditions, amplitude tapering for sidelobe control, and the extension to two-dimensional planar arrays.
