Subarray Quantization Lobe Decollimation

Page 1237.

Abstract:

This paper presents a new method for the reduction of quantization lobes produced by beam scan in an array of subarrays. These quantization lobes occur at the grating lobe angles and are decreased by the subarray pattern. It is shown that they can be further reduced by adding a random phase component to each subarray. For two element subarrays the quantization lobes (QL) suppression is roughly 10-12 dB.
