Abstract:

Previous detection studies assumed that a target was either present in a region of interest with a probability p, or not, with a probability 1-p. Knowing the value of p, the searcher makes a measurement of a random variable that has a probability density function which depends on whether or not the target is present and attempts to make a decision regarding the presence of the target. In this paper a more general point of view is adopted in that the author allows the possibility of both target and non-target elements to be present in any region of measurement. This provides an explicit consideration of a third possibility, that of a mixture of target and non-target elements. The forms of the probability densities for the mix variate are obtained for a variety of assumptions regarding the relationships among the variates involved. A sequential decision problem is extended to include the three value case.
