Abstract

This paper presents an analytical method to effectively and rapidly evaluate the impact of airframe suppression on electro-optical/infrared (E-O/IR) system lock-on range. This method is known as the Effective Rapid Airframe Suppression Evaluation (ERASE). It can be used to perform tradeoff analyses with respect to IR suppression systems and evaluate the impact of these systems on E-O/IR systems. This paper discusses a new set of dimensionless equations and how these equations are used to evaluate changes in airframe area, temperature, emissivity, and reflectivity (as a function of earthshine, solar reflections, and skyshine). Since the ERASE code has been formulated as a rapid computational tool (capable of generating over 1000 design variations in minutes), it is ideal for performing design tradeoffs against airframe shaping, thermal control systems, and diffuse reflectivity/emissivity control. Results from the ERASE code are presented using Grumman's System for IR Evaluation/Contrast Generator Code (SIRE/CONGEN) as input.
