Abstract
Spatial dithering of subarrays is a technique that allows the array to continue to function with coherent interference. Spatial dithering of subarrays yields a cascade array structure. It is shown that it is not necessary to sacrifice array aperture when using dithering. A formula for the resultant SINR (signal-to-interference-and-noise-ratio) is derived. Only one array was used to compute the output of the array. Adaptively combining the output of the subarrays resulted in improved SINR
