Paper Abstract

In this work, we focus on developing the infrared (IR) sensor and performance analysis model for space-based IR systems which are designed for detection of space targets in the earth and the earth-limb background. Corresponding to the sensor observation geometry, a simplified transmittance calculation scheme applicable to large-scale scenes as well as a mathematical model for pixel-by-pixel irradiance calculation is proposed. By defining the apparent contrast of targets in simulated IR images, a model for detection performance analysis is developed for sensors operating in different spectral bands. Typical simulation examples are presented to validate the current model and methodology.
