    Abstract: Methods and apparatus for a phased array radar system including an array comprising columns of super-elements containing radiator elements located along a length of the super-element, wherein the super-elements form the columns such that super-elements are arranged end-to-end, wherein the super-elements are arranged in the column at randomized locations to reduce sidelobes. In a further embodiment, super element lengths can be randomized.

    Abstract: Described embodiments calibrate an array antenna using near-field antenna measurements individually for each antenna element in an antenna under test (AUT). A signal is received at a first AUT antenna element from an antenna probe assembly by transmitting from the antenna probe assembly at each of multiple known probe locations in a near-field of the AUT. A signal is received at each probe location by transmitting from the first antenna element of the AUT to the antenna probe assembly. The received signals are combined into a combined signal for the first antenna element that de-correlates multi-path in the combination result. The combined signal is processed to generate a calibration coefficient for the first AUT antenna element. Remote boundary condition (RBC) testing is performed to reduce temporal instability. The multiple known probe locations lie on one of the following: a planar surface, a cylindrical surface, and a spherical surface.
