Abstract

A number of infrared passive surveillance receivers are analyzed with the theory developed in a previous paper. The specific problem of interest is the detection of low-contrast point source targets against high-contrast structured backgrounds. A new and promising approach to signal processing is proposed for minimizing background-induced false alarms while retaining maximum target detection sensitivity. We show that time-delay and integration detector technology may afford us excess detector sensitivity that we can intentionally sacrifice in the interest of enhanced performance against structured scenes.
