ARRAY REDUNDANCY FOR ACTIVE LINE ARRAYS

Active imaging arrays are used to image scenes composed of reflectors of transmitted radiation, and in many such applications, line arrays a re employed, In this paper, we discuss scanned active line arrays for imaging based on image synthesis, We define the novel concept of array redundancy for active arrays, analogous to the well-known concept of redundancy applied to passive arrays, and we define and give examples of minimum redundancy and reduced redundancy line arrays composed of t ransmit/receive elements, Such arrays differ from their passive imagin g counterparts both in geometry and in element count.
