Abstract
Difference bases are discussed and their relevance to sensor arrays is described. Several new analytical difference base structures that result in near optimal low-redundancy sensor arrays are introduced. Algorithms are also presented for efficiently obtaining sparse sensor arrays and/or difference bases. New bounds, related to arrays that have both redundancies and holes in their coarray, are presented. Some extensions to the idea of difference bases that may yield useful results for sensor array design are discussed
