DEVELOPMENT OF LEAD SELENIDE DETECTOR ARRAY, VOLUME I. PASSIVE DETECTION STUDY.
Abstract
In Volume I of this two-volume report we concentrate on the theoretical considerations pertinent to the design of the preprocessor. In Section 2, we describe the boundaries within which the preprocessor studies have been conducted. In Section 3, we discuss possible performance criteria for assessing the preprocessor and define, in terms of these criteria, the ideal preprocessor. We point out the difficulties involved in selecting the most appropriate criterion (or set of criteria), and in using it to compare the performance of alternative preprocessor designs, when the problem of designing the optimum preprocessor is - as in our case - put in very general terms. In Section 4, we study all relevant conceptually realizable linear operations, and choose - within the requirements and constraints imposed by the Statement of Work - a set of such operations; this set of operations constitutes, by definition, the ''perfect'' preprocessor. We point out in this section that the requirement that the preprocessor operate with a target image speed as high as 1000 photoconductors per second, together with the constraint that the shortest observation interval shall not be less than one millisecond, make it impossible to provide a satisfactory scheme for background rejection. In Section 5, we state in what respects the set of operations chosen for the proposed preprocessor differ from those chosen for the perfect preprocessor. (Author)
