Abstract : This report is in four parts. The first part is an article presented at the February 1983 meeting of the IRIS Specialty Group on Targets, Backgrounds, and Discrimination. Since the text is classified CONFIDENTIAL, it is not included here. Instead the article is represented by a page giving the unclassified title, the authors, and a reference to the symposium proceedings where the text can be found. The work leading to the IRIS article uncovered deficiencies in the methods of manipulating recorded clutter data to study the effect of spatial resolution on clutter rejection and signal detection. The second part of this report notes the deficiencies and indicates whether and how they can be corrected. One of the correction techniques will be described in a future article after it has been tested and proven by computations. Part 3 is an article which reports the results of studies to elucidate the operation of an adaptive threshold sensor and to determine how its size affects signal detection. This article has been submitted for publication in the journal, Applied Optics. Finally, part 4 summarizes work done to obtain data suitable for simulating two-dimensional signal processing.
