Paper Abstract

Design criteria for IRST systems are investigated based on calibrated imagery of sea backgrounds under different weather conditions with and without fixed and moving point targets. Image sequences are taken using the GEC DUWIR camera (3 - 5 and 8 - 12 micrometers ) equipped with a 2 degree(s) field-of-view (FOV) telescope. Image sequences of backgrounds are analyzed with respect to their inherent `point structure content' for complexity classification using a specific multi window operator. The behavior of the fixed point targets with respect to apparent spatial and temporal intensity variations in the imagery is separated into atmospheric and sensor systems effects. The original imagery [image sequence: 25 Hz, instantaneous field-of-view (IFOV): 0.08 mrad] is used with reduced spatial and temporal resolution to test point detection and tracking algorithms for realistic IRST sensor layouts. Various optical and signal processing configurations were explored and merits of each are discussed in this paper.
