title: Infrared surveillance. 1: Statistical model.
abstract: A new procedure is presented for calculating the performance of scanning background-limited IR sensors with adaptive threshold signal-processing logic. The IR background scene is presumably specified as a radiance map of arbitrary (but deterministic) structure. The nonstationary statistical nature of the photocur-rent is taken into account by combining some results from optical communications theory with a formalism for the threshold-crossing statistics of nonstationary noises. The present work is extended in a companion paper in which various simplifying approximations and illustrative numerical examples are presented. The theory developed in these two papers is applicable to design studies for IR passive surveillance devices.
