Speaker(s):  Randy L. Haupt

Radar designers suppress sidelobes in the radiation pattern of a phased array antenna in order to avoid picking up objectionable amounts of ground clutter and other spurious signals. Two‐way antenna patterns result from the product of the transmit array pattern times the receive array pattern. Radars often have sidelobe specifications for the two‐way pattern. The traditional approach to synthesizing a two‐way pattern is to prescribe low sidelobe tapers for the transmit and receive patterns then assume that the peak two‐way pattern sidelobe level equals the peak transmit pattern sidelobe level time the peak receive pattern sidelobe level. This talk presents several approaches to directly synthesize two‐way array factors. Examples include linear and planar arrays.
